Section 1: Contextual Factors:
School and Community
Church Street School is a pre-kindergarten – 6 grade elementary school serving 371 students
with a faculty base of 30 teachers. Of all the students in the school, 80.3% of these students are
eligible for free/reduced price meals, 14.6% of the students are not fluent in English, and 6.8%
have disabilities.
Church Street Elementary School has a diverse student population drawing from several
neighborhoods in close proximity to the school. Approximately 50% of our students are Black,
20% are White, 25% are Hispanic and 5% are Asian. Languages spoken at home include
English, Spanish, Italian, Greek, Albanian, Arabic, Bengali, Chinese, French, Hindi, Malay,
Turkish, Urdu, Vietnamese, Uzbek and Cantonese.
The school is set in an urban and very diverse socioeconomic community. Church Street School
is set in Hamden which consists of families of low, middle, and high socioeconomic statuses.
However, according to the eligibility of free and reduced price meals, a large majority of the
school’s families are of low socioeconomic status. Approximately 73% of Hamden’s population
are White, 13% are Black, 0.26% are American Indian, 16.5% are Hispanic, 3.8% are Asian, and
2.9% are multi-racial.
The improvement of literacy is an ongoing initiative in this school. This year, Church Street
School increased its literacy support by hiring an additional literacy specialist and two additional
Title One tutors. The school implemented consistent instructional strategies in Literacy using
shared, guided and independent reading and provided interventions for students below
benchmark in reading. Using the data team process, teachers meet weekly to develop data cycles
in literacy in collaboration with the external data facilitator. In order to improve instruction for
2015 Student Teaching Work Sample Plair 4
all students, three resource teachers worked closely with classroom teachers, media specialist,
literacy specialists, ELL tutors and support staff to develop individualized programs based on
current and on-going assessments. Lexia and Head sprouts, a bilingual aide, peer tutors,
Experience Corps volunteers and university students were part of intervention plans using the
SRBI model. CMT scores indicated a continued need for improvement in reading. Summer
programs to support literacy included free school-based initiatives with a focus on vocabulary
development for 15 students scheduled to enter kindergarten, 40 students entering grades 3 and 4
and ECO Science Camp for 46 students entering grades 3-6.
Classroom
Room 12 is one of 3 first grade classrooms at Church Street with a total of 15 students: 6 boys
and 9 girls. 3 of the students have IEPs for speech impairment and one has both a speech
impairment and a seizure disorder, for which she has a full-time one-on-one aid by her side. Two
students are ELLs, both of whom had Spanish as their native language. Concerning ethnicity, 2
of the students are White/Caucasian American, 3 are Hispanic, 1 is Asian from the Middle East,
and the remaining 9 are Black/African American. For the ELL students, intervention specialists
pull them out for some one-on-one language training. For the students with IEP’s, it is required
by the school that they get a certain amount of hours on the educational apps on the school iPads.
According to their DRA scores, the majority of these students are considered on grade level
when it comes to reading.
The teacher uses responsive classroom techniques to manage her classroom. She follows a strict
behavioral/reward system used by the entire school called bucket fillers. This really keeps the
students motivated in monitoring their own behaviors. As for instruction, the teacher uses lots of
games and active hands-on types of materials that keep the students engaged in their lessons. She
2015 Student Teaching Work Sample Plair 5
uses songs and rhymes as well to help the students memorize key concepts and ideas. Also, the
teacher always askes intriguing questions to tap their prior knowledge and get them thinking.
Structural wise, students are grouped in small groups all the time, unless they are on the carpet
for morning meetings or group lessons. After group mini lessons and instructions, students work
in groups in work stations for both math and reading for the remainder of the academic block.
Section 2: Learning Goals and Objectives:
The content area of this unit is first grade mathematics. There will be three-four lessons,
including a pre and post assessment. The overall goal of this unit will be using addition and
subtraction to solve story problems. The three lessons of this unit that I will teach will have one
overarching goal in the whole number operations math strand:
Learning Goal #1: Students will make sense of and develop strategies to solve addition and
subtraction problems with small numbers.
Objective 1: Students will be able to visualize and demonstrate, using an equation the action in
subtraction situations involving removal
Objective 2: Students will be able to subtract one number from another, with initial totals of up
to 12
Objective 3: Students will be able to develop and use various strategies for solving subtraction
(removal) problems
Objective 4: Students will be able to model the action of a subtraction (removal) problem with
counters or drawings.
2015 Student Teaching Work Sample Plair 6
2015 Student Teaching Work Sample Plair 7
Additional standards for mathematical practice aligned
with the objectives of this unit include the following:
MP2: reason abstractly & quantitatively
MP4: model with mathematic
MP5: use appropriate tools strategically
MP7: look for & make use of structure
Section 3: Assessment Plan:
Pre-assessment – The pre-assessment will be a worksheet
that I create myself that reflects the objectives that I want
students to be able to do by the end of this unit. The
intention is to help me determine the knowledge gaps and
misconceptions that students have from the previous year
of instruction. It is crucial that these gaps and
misconceptions are identified and addressed throughout
instruction of this unit. Failure to do so will result in
frustration for both students and myself, as math is a
supremely cumulative subject.
2015 Student Teaching Work Sample Plair 8
The pre-assessment will be graded out of 10. The first question will be worth 2 points. 1 point for
if they can show that this is a subtraction problem, and 1 point for giving the correct answer. For
the second problem, students can receive 2 points, 1 for each strategy. The third problem is
divided up into 4 smaller problems and is thus worth a total of 4 point. The last question will be
worth two points. If students modeled the subtraction properly with a drawing, they receive one
point. If they just answer the question without any picture, they receive one point. If they draw
an accurate model of the subtraction situation and answer the question correctly, they receive
two points. If a problem is left blank, the student will not receive any credit.
Results of this pre-assessment may also lead to identifying the specific needs of my lower level
students with disabilities, as well as my English language learners. The pre-assessment also
contains material that will be covered in this unit. If a student has already mastered some or all of
the material that is contained within this unit, accommodations will be made for the advanced
student as well, allowing them to progress to more challenging material. Differentiation is not
easy, but we all know that students become bored, either because they are behind or because they
are waiting for more challenging material. In this case, differentiation is very manageable –the
advanced student will be offered double-digit numbers to subtract, starting with problems where
there is no borrowing and then including borrowing if they can handle it.
Formative assessments – These will be concise assessments, intended to measure the learning
targets for this unit in small intervals and inform lesson planning for subsequent sessions. These
assessments will be on going and varied. We will have worksheets from time to time as well as
games or quick assignments. Homework may also be used as a formative assessment for me to
see what needs to be taught, skipped, re-taught, or enforced and with what students. Verbal and
informal assessment will often be used at the end of a lesson during discussion or at the
2015 Student Teaching Work Sample Plair 9
beginning of a lesson to see what they already know or what they remember from the previous
lesson.
Post- assessment – By the end of this unit, students are expected to demonstrate a mastery of the
basic material presented on this assessment. Student performance on the final assessment should
continue to inform the teacher regarding the gaps and misconceptions that students may still
possess relative to this material.
The post-assessment will be summative. It will be a worksheet very similar to the pre-assessment
to see how much the students actually learned as a whole class. Individual student growth will
also be monitored to determine how effective my teaching instruction and strategies were.
The four learning objectives that the students will be assessed on are:
Can students demonstrate with an equation the action in a subtraction story problem?
Can students subtract one number from another with initial totals up to 12?
Can students use and record strategies for solving subtraction problems?
Can students model the action of subtraction using counters and/or drawings?
Similarly, the post-assessment will be graded out of 10. The first question will be worth 2 points.
1 point for if they can show that this is a subtraction problem, and 1 point for giving the correct
answer. For the second problem, students can receive 2 points, 1 for each strategy. The third
problem is divided up into 4 smaller problems and is thus worth a total of 4 point. The last
question will be worth two points. If students modeled the subtraction properly with a drawing,
they receive one point. If they just answer the question without any picture, they receive one
point. If they draw an accurate model of the subtraction situation and answer the question
correctly, they receive two points. If a problem is left blank, the student will not receive any
credit.

Section 4: Design for Instruction:
My pre-assessment was given the week before my unit was planned to be taught. Students are
still deeply embedded in addition problems and have not yet seen the connection between
addition and subtraction. Students were briefed before taking the pre-assessment to let them
know that they were not expected to know how to solve subtraction problems. They were told to
simply try their very best and that I only wanted to see what they already knew about subtraction.
After the assessment, students were then debriefed to ensure that they understood that it was OK
that they did not know how to do the pre-assessment. Next week they would learn all of the skills
they needed to ace this test.
During the pre-assessment, I equipped all the students with their own worksheets and
administered the test verbally to the students. Students were asked to read along with me as I
explained their job for each question. After every question I gave the students some time to
complete the problem before moving on to the next.
In order for a student to be considered proficient at the objective the students must score a 3 or 4
(on problem #3 only) and a 2 on all other problems on the pretest or posttest. Students who are
proficient have shown that they have mastered the respective content objectives. Students who
are basic score a 2 (on problem #3 only) and a 1 on all other problems on the pre or post
assessment. Students who score a 0 on the pre or post assessment are considered below basic. A
score of below basic means that the student does not indicate any understanding of the concepts
presented in the content objectives.
The pre-assessments were graded according to the criteria rubric explained on page 9.
The data displayed below shows the student performance relative to the entire pre-assessment as
a whole and then student performance relative to each of the learning objectives.

Analysis of Pre-Assessment
Student performance on objectives 1, 2, and 3 were as expected. On the other hand, more than
half of the students were proficient at objective 4. Because of this I will focus less on picture
modelling of a subtraction situation and introduce things like using a number line or
decomposition to help students model/solve story problems. This means that for the students who
were not proficient at objective 4, they will learn the process of drawing circles or some sort of
figure and crossing out a given amount to find out what is left. However, for the students that
were proficient, I will encourage them to use some of the other strategies such as drawing a
number line, using addition facts, and decomposition.
As far as differentiation, there are about 5 students that I know need to be further challenged and
about 5 that need explicit support. I have modified all my lessons with a plan to help all of my

1.0A.1: Use addition and subtraction within 20 to solve word problems involving situations of
adding to, taking from, putting together, taking apart, and comparing, with unknowns in all
positions, e.g., by using objects, drawings, and equations with a symbol for the unknown
number to represent the problem.
1.0A.5: Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
1.0A.6: Add and subtract within 20, demonstrating fluency for addition and subtraction
within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 =
14); decomposing a number leading to a ten; using the relationship between addition and
subtraction; and creating equivalent but easier or known sums.
1.0A.7: Understand the meaning of the equal sign, and determine if equations involving
addition and subtraction are true or false.

2. Rationale
The objective focuses on two of the four CCSS critical areas for Grade 1: Operations and Algebraic
Thinking as well as Number and Operations in Base Ten. The CCSS outline the mathematics concepts
that should be the focus of instruction in Grade 1 and while each area is important for laying the
foundation for future study of mathematics, these two are considered to be most predictive of future
mathematics learning. Students who leave first grade with a proficient grasp of these two concepts and
skills will largely be prepared to begin second grade mathematics.
2015 Student Teaching Work Sample Plair 21
Students retell and solve a story problem in which one amount is removed from another. They think
about how the problem is similar to and different from stories about combining two amounts. Students
learn and play subtraction variations of Roll and Record and Five-in-a-Row.

4. Objectives
Students will be able to
visualize and retell the action in subtraction situations involving removal
Subtract one number from another, with initial totals up to 12
Use numbers and standard notation (+,-,=)
5. Procedure
Initiation
10-15 minutes
Tell students a subtraction story.
Do not alert students to the fact that this will be a different type of story: instead,
encourage them to follow the same routine of visualizing the action of the story.
The teacher will discuss how this kind of story is different from those that students
have been solving after students have heard, retold, and solved the problem.
Story problem: Max had 9 toys. His friend Rosa came over to play with him. Max
gave 3 of the cars to Rosa to play with. How many cars did Max have then?
Encourage students to visualize the action in the story.
Ask students to retell the story after they have heard it. (Students may alternatively
turn and retell the story to a partner). After students have had a chance to retell the
2015 Student Teaching Work Sample Plair 22
story, ask students whether Max will have more or fewer cars at the end of the
story.
Possible student responses: Max has more cars at the end of the story; Max has less
cars at the end of the story.
Finally, ask student to solve the problem. Give each student a tower of 9 cubes to
use as needed.
Ask several students to share strategies for solving the problem. These might
include
Breaking 3 cubes off the tower of 9 and counting how many are left
Counting backward (on a number line, mentally, or on their fingers)
Counting up from 3 to 9
Thinking about addition (“I know that 6 and 3 together make 9”)
As you discuss strategies, focus on developing language that helps students acquire
an image and understanding of the action of subtraction: take away, went away,
give away, separate, remove, less, fewer, and so on. However, do not use the words
subtraction or minus yet. Those words will be introduced in the next lesson.
Instead, use the above vocabulary.
Ask students to think about how this problem is different from the problems they
have been solving.
Students might say:
“Max ends up with less. In the other problems, the person usually ends up with
more.”
“Usually we put two numbers together and find out how many. This story is
different because you have to take some away. “
Lesson
Development
20 minutes
Introduce subtraction games for Math Stations.
Remind students that when they play Roll and Record and Five in a Row, they
always roll two cubes, and have so far combined the rolls to figure out what
number to write or what number to cover. Today, instead of adding, they are
going to be subtracting.
Show students the number cubes they will be using to play. The 1-6 dote cube
will be familiar to them. Take a minute to look at and establish what numbers
on the new number cube (7-12).
Explain to students that they will roll both cubes. The number cube tells them
how many cubes they start with. The dot cube tells them how many cubes to
subtract, or take away, from that.
2015 Student Teaching Work Sample Plair 23
Play a few sample rounds to demonstrate. Give each student 12 connecting
cubes to use as needed, and then roll the number cube and the dot cube.
Say: Let’s say that I rolled a 9 on the number cube and a 2 on the dot cube. I’m
going to start with the bigger number (9) and take away the smaller number (2).
The answer to 9 take away 2 will tell us what number to write on our recording
sheet.
Ask a few students to share how they would solve this problem. Possibilities
include:
Using the cubes
Counting back mentally on their fingers or on a number line
Using an addition combination they know
Counting up from 2 to 9
Students might say:
“I made a tower with 9 cubes, and I took away 2 of the cubes.”
Continue with other examples until students understand how to play and record
for Roll and Record: Subtraction.
Quickly review the rules for the second game: Five in a Row: Subtraction.
Students will again be very familiar with this game. Be sure to point out that
we be using a number cube and a dot cube. We will subtract the smaller
number (on the dot cube) from the larger number (on the number cube). They
will then use a counter to cover the result on their game board. The goal is to
completely cover one row horizontally, vertically, or diagonally.
Students will be grouped based on academic ability. Based on the pre-
assessment that I gave the week before, I had a pretty good idea of who
understood the basics of subtraction and who did not. Thus, I decided to place
students who were competent with students I thought would struggle. That way
they could help them out and really get the most out of the games.
Closure
10 minutes
Pose another story problem or two for students to retell and solve as a
whole group. Remember to ask students whether the end result will be more than or less
than the initial amount.
1. Toshi had 8 pennies. He went to the store and bought an apple for 5
pennies. How many pennies did he have left?
Students might say:
“First, I put up 8 fingers for the 8 pennies. I had to take away 5 fingers –that’s
one whole hand of fingers. Look, I have 3 fingers still up.”
2015 Student Teaching Work Sample Plair 24
2. Libby had 10 crackers for a snack. She shared them with her friend Neil.
She gave Neil 4 crackers. How many crackers did Libby still have?
Students might say:
“I built a tower of 10 cubes for the 10 crackers. Then I took off 4 cubes. Six are
left -1, 2, 3, 4, 5, and 6.”
6. Assessment
Ongoing assessment: Observing students at work
The games provide the students practice with subtracting small numbers and with writing
numbers.
How do students determine the problem that a given roll represents? For example, if they
roll 3 and 7, how easily do they know or figure out that the problem to solve is 7-3?
How do students solve the problem? Do they use counters? Their fingers? A number
line? Do they work mentally? Do they count all, remove some, and count again? Count
back from the total number? Count up to the total number? Use an addition fact they
know?
Are student able to accurately and legibly record the results?
The teacher will use the on-going assessment chart and go around to every student during
our workshop games.
Homework: Student Activity Book pg. 20
7. Reflection
The lesson as a whole went well. Based on the pre-assessment, I understood that the students would need
sometime before subtraction would come more naturally to them. The majority of the students did not
understand the action taking place in the first story problem. I had to model the action of taking away and
removal to find what is left quite a few times before I felt that students could do it themselves. All
students were very engaged and very interested in understanding what subtraction was, which was great.
The lesson was exciting for them and they were eager to learn and play. The games are a very great way
to keep the students engaged at the end of the day. I will definitely try and incorporate a game into every
workshop of this mini-unit. The students need and love them.
If I could teach this lesson again, I would definitely not group students based on academic ability. First of
all, the pre-assessment wasn’t that good of a pre-judge into the academic abilities of the students. Student
that I thought would struggle did ok and some student that I thought would do fine, needed some extra
help. Instead I would let students pick their partners so that they are grouped with people that they know

8. Modifications/Differentiation
Student A This student will need some extra support
determining the problem to solve after
rolling the cubes.
The teacher will ask the student to tell her
which cube shows the larger number.
Remind the student that you start with the
larger number and take away the smaller
number. The final answer will be what is
left.
Student B This student will need some extra support
determining the problem to solve after
rolling the cubes.
The teacher will ask the student to tell her
which cube shows the larger number.
Remind the student that you start with the
larger number and take away the smaller
number. The final answer will be what is
left.
Student C This student will be given a behavior
modification.
The teacher will incorporate instant bucket
slips for appropriate behavior. This includes
student working cooperatively with his
partner, taking turns, being respectful,
sharing items, and following the teacher’s
instructions without argument.
Extension for Student X (if necessary)
If they quickly gets the hang of subtraction, encourage him to use different strategies to figure out the
solution. For example, if he is used to using his fingers or doing the math mentally in his head, encourage
him to try counting down, or counting up, or even using his addition facts to solve the problems.
they work well with and would be comfortable diving into new information with. Because I did not do
this, some students were frustrated with their partners because they did not work well together on top of
the frustration that they were feeling from not quiet understanding the concept of subtraction.
Also, as far as management goes, I would introduce the idea of jobs to students, such as forming our ten
rods, after fully giving my instructions for the lesson. Students were more interested in these jobs than in
understanding what they were supposed to do once they started their workshops.
Finally, during clean up, instead of just telling students to clean up their stations and return their supplies,
I could have done much more to make this transaction much more orderly. I could have called certain
tables up one at a time and placed the bins that they would return their number cubes and counters in
some place that was easily accessible. As soon as students were done returning their supplies they could
hand their papers into to me and take a seat on the carpet.

10. Rationale
The objective focuses on two of the four CCSS critical areas for Grade 1: Operations and Algebraic
Thinking as well as Number and Operations in Base Ten. The CCSS outline the mathematics concepts
that should be the focus of instruction in Grade 1 and while each area is important for laying the
foundation for future study of mathematics, these two are considered to be most predictive of future
mathematics learning. Students who leave first grade with a proficient grasp of these two concepts and
skills will largely be prepared to begin second grade mathematics.

Students solve subtraction story problems in which they find how many are left when one quantity is
removed from another. They record their solution strategies individually and then share their strategies
with the class.

12. Objectives
Students will be able to
visualize and retell the action in subtraction situations involving removal
develop strategies for solving subtraction (removal) problems
Model the action of subtraction (removal) problems with counters or drawings
Develop methods for recording subtraction (removal) strategies
13. Procedure
Initiation
10-15 minutes
Tell students a subtraction story.
Pose one or two subtraction stories for students to retell and solve.
Story problems:
1. Felipe found 7 seashells on his trip to the beach. When he came home,
he gave 1 of them to his sister, Martha. How many shells did he still
have?
2. Seth was playing at the part with 6 of his friends. Two of them had to
leave to go home for dinner. How many were still at the park?
These problem provide a good opportunity to talk about what happens when you
take away only one or two things from a group. Focus some discussion on counting
backward (in their heads, on their fingers, and/or on the class number line) as one
strategy for solving this kind of problem because this can be a powerful strategy for
students to consider.
Ongoing assessment:
Can students retell the story to a partner accurately?
Can students figure out the action taking place (subtraction or addition)?
Can students come up with a strategy for solving this kind of problem?
2015 Student Teaching Work Sample Plair 28
Have students come up to the board and share their ideas:
Verbally have students retell the story.
The teacher will then write it down.
Beneath the retell, have students volunteers come up to the board and write an
equation that demonstrates the action that must be taking to solve the problem, but
do not solve the problem.
Then have students brainstorm some possible strategies that they could use to solve
this problem. Write them underneath the equation.
(Strategies may include
Breaking cubes off the tower and counting how many are left
Counting backward (on a number line, mentally, or on their fingers)
Counting up )
Finally, ask student to pick one of the strategies and solve the problem. Have a
volunteer come up to the board and circle the strategy that they used, demonstrate
the strategy, and write the answer.
Lesson
Development
30 minutes
Read aloud the problem on student activity book page 21 and 22, and ask two
or three students to put the story in their own words. Keep the emphasis on
retelling the story and not solving it.
1. There were 12 squirrels on the ground. Then 4 of them ran up a
tree. How many stayed on the ground?
2. I saw 15 squirrels in the park. Then 8 ran away. How many
squirrels were left?
These two story problems will be our first station.
The next station will be subtraction bowling. Review with the students how we
play bowling and model one round. Go over the bowling recording sheet.
Directions: Students will be using 10 cups and a ball. They will roll the ball in
the array of cups and record how many get knocked down. They must then
subtract how many were knocked down from how many they originally had to
answer the question of how many are left. They must simply count the
remaining cups, and record that number after the equal sign.
2015 Student Teaching Work Sample Plair 29
Then have the students break off into their stations. Each station will be 15
minutes. There will be two stations.
Station 1: Story problems page 21 and 22
Station 2: Subtraction Bowling
For the story problem, students must show their work.
They need to give me an equation and name a strategy before solving the
problem.
Possibilities include:
Using the cubes
Counting back
Using an addition combination they know
Counting up
Closure
15 minutes
Bring everyone back to the carpet for discussion and sharing.
Have students share their answers for the two story problems: equations,
strategies and final answers.
Have students share some of their bowling results.
Wrap up with having students review the strategies for subtraction.
14. Assessment
Ongoing assessment: Observing students at work
The problems provide the students practice with subtracting small numbers and with writing
numbers.
How do students determine the problem that the story presents? For example, if they see
a 3 and 7 in a problem, how easily do they know or figure out that the problem to solve is
7-3?
How do students solve the problem? Do they use counters? Their fingers? A number
line? Do they work mentally? Do they count all, remove some, and count again? Count
back from the total number? Count up to the total number? Use an addition fact they
know?
Are student able to accurately and legibly record their results?

These students can solve the given
problems easily and can record their
strategies well.
The teacher will ask these students to show
a second way to find the answer or solve a
related problem with larger numbers.
Struggling
students
These students need more support solving
the problems and modeling the situations.
The teacher will re-read the problem with
students who are having difficulty getting
started and encourage them to tell the story
in their own words. Some may need help
directly modeling what is happening in the
situation by using counters.
Today’s lesson went a little better than yesterday. I changed up my groups and that seemed to help. The
students seem to be getting the hang of subtraction. We went through the process of answering story
problems with retelling the action with an equation, picking a strategy, and then using the strategy to
solve the problem. Some students still need some extra help with this but most students seemed to
understand it.
Roll and record seems to be a struggle for some of my students, even though they have played this game
many times with addition. The concept of subtraction is something that they need more time to be
immersed in before it will start coming naturally to them.
According to yesterday’s homework, students understand the missing addend problems quite well. My
formal and informal formative assessments are showing me that the students just need more exposure. So
at the beginning of every lesson I will be holding quick subtraction drills using the number line, mental
math, and counting on/counting backwards strategies.
I feel the need to give the strategies that students already know of and do a name, so that they can identify
them and talk about their problem solving processes.

Today’s lesson showed me that my students all know how to subtract. The problem comes when they are
required to figure out whether they are supposed to subtract or add. Figuring out this difference is hard
for them. However the actual process of solving a subtraction story problem, modeling it with an
equation, choosing and using a strategy, and solving the problem is not hard for them. At this point I have
been trying to get it through to the students that they don’t have to figure out whether this is a subtraction
or addition problem. All of the problems for this week are subtraction problems.
Tomorrow, we will review everything we learned in the last 3 days, in preparation of the post assessment
I will give on Friday.

Section 5: Analysis of Student Learning
After reviewing the post-assessments, I have concluded that my students have learned a
phenomenal amount of knowledge when it comes to the concept of subtraction in just these last
four days. If students received a total of 70%-80%, they were considered proficient. If they
received a total of 90%- 100%, they were considered goal or exceeding expectations. All of my
students fell within these two ranges. With the mass majority falling in the 90%-100% range. I
was very impressed.
To further analysis the results of this unit design and I have analyzed the results of my pre-and
post-assessments in several different ways. The first will be an analysis of the pre and post
assessments of the entire class in respects to every students on every learning objective. The
purpose of this analysis will be to see the individual and average progress of my students from
pre- to post-assessment.

stagnant. Everyone received a better grade on their post assessment than they originally had on
their pre-assessment.
Figure 6: Average student progression from pre to post assessments.
As a whole, the progress of my students’ knowledge and skills, when it comes to the learning
objectives designated for this unit, is very apparent in the graph above. The average achievement
grade on the overall test was 43% for the pre-assessment; the average achievement grade for the
post-assessment was 88%. For LO1, average student achievement rose from 37% to 80%. For
LO2, the average student achievement increased from 57% to 95%. For LO3, average student
achievement rose from 7% to 70%. Finally, for LO4, the average student achievement increased

The next form of analysis will be an analysis of the pre and post assessments of the class in terms
of subgroups based on a specific characteristic. The achievement of these subgroups will be
compared in respects to only one learning objective. The purpose of this analysis will be to see
the achievement and average progress of my students from pre- to post-assessment, when
organized into different groups. I chose performance levels to be the characteristic that I based
my subgroups on. I came to this conclusion based on student performances on the pre-
assessment. There were three distinct levels of performance: proficient, basic, and below basic.
Subgroup 1 were proficient meaning they scored a 70-80 on their pre-assessment. Subgroup 2
were basic, meaning they scored a 30-50 on their pre-assessment, and subgroup 3 were below
basic, meaning they scored a 0-20 on their pre-assessment. Surprisingly, having a class of 15
students, 5 landed nicely in each of the three subgroups. The learning objective I chose to
analyze these subgroups in was LO3. This is the objective that students showed the most
interesting growth in, seeing how they all had no prior knowledge of the concept. Learning
objective #3 stated that students would be able to identify strategies that they could utilize to
solve subtraction problems. The average student achievement in this objective was 70%. But
how did each subgroup compare when dealing with this objective? The graph below shows the
comparison between the three subgroups in reference to the third learning objective.
2015 Student Teaching Work Sample Plair 38
Figure 7: Performance level subgroups comparing results of post assessment.
The student progress on this objective is simply amazing. Subgroup 2 is the only subgroup that
had any points for this objective, because two student out of this group were able to determine
that the question was asking them to subtract. Because of that, I awarded them a point. However,
not one of the students in any of the groups understood how to identify any strategies for solving
subtraction problems. Because of this, students made the largest growth in this objective, even
though the average student achievement across the objectives was lowest in objective 3. Even so,
when you compare the subgroups another story is told. Subgroup 1 completely mastered this
objective, scoring a total average of 100% on their post assessment. Subgroup 2 scored a total
average of 80% on this objective, proving them proficient. Subgroup 3 received a total average
score of 50%, proving them basic. This group is the factor that slightly skewed the data for this
objective. However, these results are understandable considering the academic abilities of each

subgroup. Subgroup 1 consisted of my brightest students. Subgroup 2 were my average students,
and subgroup 3 happened to consist of my more struggling students.
The last form of analysis will be an analysis of the pre and post assessments of the class
in terms of individuals. I will select two students that demonstrated different levels of
performance, picking one student from my high performance group and another student from my
low performance group. The two students I will be analyzing will be student #6 and student #15.
It is very important to understand the learning of these two students seeing how they were very
different when it came to learning abilities, learning styles, and performance levels. Student #6
was one of my students who did not make any progress in LO1, which was a very important
objective that showed that students can demonstrate they understand the action being asked of
them in a subtraction problem. Student#15 did not show any progress either. However, their
reasons as to why they didn’t make any progress are very different. On the one hand, Student #6
came into the pre-assessment with zero knowledge of this objective. This student definitely came
out of this unit with lots of knowledge in this area, however, his post-assessment failed to show
this. He ended up scoring a zero for this section again. On the other hand, Student#15 came into
the pre-assessment with complete knowledge of this objective. This student came out of this unit
with a new assurance and deeper understanding of this objective, while his post-assessment
simply showed that he scored 100% on this section. For each student’s overall achievement, they
both showed progress in their level of understanding of subtraction in general. However, both
received differentiation. Student #15 often received alternative worksheet to work on and dealt
with higher two digit numbers when it came to subtraction. Student #6 received more of the
teacher’s one-on-one time and repeated explanations and demonstrations. Student #6 also was
given extra tools such as the print out number lines to assist him in computations. He also never
2015 Student Teaching Work Sample Plair 40
had to deal with numbers larger than 12. This student required lots of re-directing and focusing.
With these adjustments and modifications, I am confident that both of these extremely different
students received the materials and support they both needed to learn something new and retain
their knowledge throughout this unit. According to several of the formative assessments during
and after lessons, as well as the post-assessment, I confirmed that these students attained the
learning goals and objectives for this unit. And even though student #6 showed no progress in
the problem designated for LO1, several of the other questions incorporated this objective to
build on other skills and he did really well in these areas. If he did not master this first objective,
he could not have succeeded in the other objectives, which he did.

Section 6: Reflection and Self-Evaluation
When I stand back and look at the end results of this project I cannot help but to feel
extremely proud. This unit had its ups and downs but overall, I would say that it went really well.
The learning objective that my students were most successful in showing mastery was objective
4: Students will be able to model the action of a subtraction (removal) problem with counters or
drawings. Every single students scored 100% on this section of their post-assessment. One
reason for this success might be that a majority of them came into this unit having experience
modeling their work with drawings and counters. According to the pre-assessment data, 60% of
the students were already proficient in this objective coming into this unit. A reason for this
might be that they carried this skill over from their work in addition into their growing
understanding of subtraction, and it really helped. Another reason for this success might be
simply the effect of good teacher. I constantly modeled the proper procedure for solving
subtraction story problems and story problems in general. I drilled it in mini lessons, formative
assessments, homework, and station work. By the time they took the post-assessment, this type
of problem was very familiar to the students and they were naturals at solving them.
The learning objective that my students were least successful in showing mastery in was
objective 2: Students will be able to develop and use various strategies for solving subtraction
(removal) problems. One reason for this occurrence might be in part due to the fact that none of
the students showed any prior knowledge or familiarity in naming the strategies that they use
when it comes to solving problems. According to the pre-assessment, everyone received 0%
strictly in the area of naming strategies, coming into the unit with no prior knowledge. A reason
for this might be that they did not focus much on the names of strategies when they did their
addition unit. The process of naming the strategies that they would automatically do in their
2015 Student Teaching Work Sample Plair 44
heads or on their fingers seemed very foreign to them. They seemed to understand the strategies
but not their names, such as counting on, counting backwards, addition facts, or number lines.
Another reason for student’s lack of mastery might be based on the question posed in the pre-and
post-assessments. The task of naming strategies for solving subtraction problems was a part of a
larger question that asked students to find the difference between two numbers. Now we had not
spent as much time on finding the difference as some of the other skills students were expected
to learn. Because of the lack of exposure to this phrase, students of then answered with responses
of comparison, such as 6 is greater than 2 instead of the difference between 6 and 2 is 4;
completely forgetting the second part of the question to list the strategies that they would use.
Basically, many of them did not consider the phrase difference to mean subtraction; thus not
comprehending what strategies they should be listing.
This is basically a technical issue with the test itself. Students reviewed and drilled the concept
of naming strategies and I have confidence that they could all do it. What I would definitely
change as far as instruction is the amount of time and focus that I put into teaching the students
the concept of finding the difference between two numbers. Alternatively, I would simply take
out the phrase and ask students just to name two strategies they could use to help them solve
subtraction problems. This would diminish the amount of confusion that surrounded this problem
and helped students focus on the learning objective.
Two professional learning goals that have emerged for me during my experience with the
teacher work sample are meaningful differentiation and classroom management. Increasing the
chances of all students, no matter their learning abilities, to learn the skills and meet all of the
objectives of any unit is definitely something that I need work on. Sure there will always be
students that perform better than others. But how can I modify or accommodate or even motivate

students to not just work hard, but give me their best when it comes to showing what they know.
Because that is what it all comes down to when you are a real teacher. Can your students
demonstrate their knowledge and skills? They may know how to subtract and know the basic
strategies for solving subtraction problems, but unless they can prove that on a test, their scores
will not reflect it and the school will not recognize it. A step that I can take to improve in this
area is working more closely with the special education teacher. I plan to take some time at the
end of my placement to shadow and interview the special education teacher, the math coach, and
the ELL teacher to try and learn some strategies and techniques for dealing with these types of
students and getting them to perform to the full potential on tests and assessments.
The second area of improvement that I recognize that I need is in classroom management.
Ensuring that management problems, such as students being confused about instruction,
frustrated about working groups and buddy partners, lack of materials or students being
distracted by materials, do not get in the way of student learning and the allotted time of daily
learning. In a classroom such as a first grade classroom, these factors occur too often. Students
are worried about helping you erase the board or gathering materials such as magnets, or
collecting papers that sometimes the teacher’s instructions are ignored or not fully paid attention
to. The teacher than repeats instructions or has to straighten out confusion and this takes time and
effort. Creating systems such as classroom jobs, organized fashions of handing in work,
established station rotations and getting all students to stop look and listen before giving any
form of instruction seems to be the only solutions for this sort of problem.
