Unit Working With Time and Money

Essential Questions/Enduring Understandings Addressed in the Lesson

What is the purpose of standard units of measurement? Why is it important to learn about money? What are tools of measurement for money and how are they used? When should we estimate amounts of money? What are the units of money and how are they used in our daily lives? How do the units within a system relate to each other?

The choice of measurement tools depends on the measurable attribute and the degree of precision desired.

Being able to count money is a critical life skill. Time and money have distinct attributes that can be measured.

Standards Addressed in This Lesson

2.MD.8 Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?

Lesson Topic Problem Solving with Money

Relevance/Connections This will be the first time that students will have worked explicitly with money according to the Common Core State Standards. Counting and using money is a skill that should be mastered by the end of Grade 2 to support future learning. It is critical to be aware of the many misconceptions that students have about money, such as over-generalizing the value of coins when counting them. For example, students count coins as individual objects or equate a coin’s size to its value.

It is critical that the Standards for Mathematical Practices are incorporated in ALL lesson activities throughout the unit as appropriate. It is not the expectation that all eight Mathematical Practices will be evident in every lesson. The Standards for Mathematical Practices make an excellent framework on which to plan your instruction. Look for the infusion of the Mathematical Practices throughout this unit.

Student Outcomes Students will be able to count a set of coins and solve a variety of real world problems using money including representing money amounts and counting a mixed set of bills



and coins.

Prior Knowledge Needed to Support This Learning

K.CC.1 Count to 100 by ones and by tens. K.CC.2 Count forward beginning from a given number within the known sequence

(instead of having to begin at 1). 2.NBT.2 Count within 1000; skip count by 5s, 10s, and 100s. Optional: 2.NBT.8 Mentally add 10 or 100 to a given number 100- 900, and mentally

subtract 10 or 100 from a given number 100- 900.

Method for determining student readiness for the lesson

Pre-assess students’ ability to do the following:

Skip count by 5s and 10s Identify coins and bills by name and value Add a two-digit plus one-digit number Add a two-digit plus two-digit number

Since this is the first time money is introduced formally as a standard, students will needmany experiences with coin recognition and determining the value of coins before usingcoins to solve problems. These skills can be reinforced during morning meeting andthroughout the school day.

Since students have not been introduced to decimals, problems focus on whole dollar amounts or cents.

Once students have a solid understanding of coin recognition and values, they can thenbegin using the values of coins to count sets of coins, compare two sets of coins, make and recognize equivalent collections of coins (same amount but different combinations if coins), select coins for a given amount, and make change.

How will this experience help students to develop proficiency with one or more of

the Standards for Mathematical Practice? Which practice(s) does this address?

Warm Up Several days prior to beginning the unit, distribute red and yellow crayons (2 of each per group of 4 students), Resource Sheet 13: Counting by 5’s (2 copies per group of 4 students), and Resource Sheet 14: Counting by 10’s (2 copies per group of 4 students).

Ask students to work in teams of four and have the team members number off 1, 2, 3, and 4.

Have the 1’s and 3’s work together to take turns completing Resource Sheet 13, and the 2’s and 4’s work together taking turns to

quantities, not just how to compute them; and knowing and flexibly using different properties of operations and objects.”

SMP 7: Look for and make use of structure.

“Mathematically proficient students look closely to discern a pattern or structure.”

Motivation Guess How Much?

Distribute dry erase boards. Show the class a jar filled with pennies (or

buttons). Ask students to estimate how many pennies

are in the jar. Students should record their estimates on dry erase boards.

Call on students to share their estimates. Record the estimates on chart paper.

Have a few students share why they made a particular estimate.

Ask students if they think their estimate is reasonable.

Ask a student volunteer to pull out a handful of pennies from the jar and count them out loud for the class.

Ask, “If a handful is ____ pennies, does anyone want to change their estimate? Why or why not?” Allow time for a few students to share.

Now remove handfuls of pennies from the jar and place one handful at each table until no

Learning Experience

pennies are left in the jar. Have students at the tables place their pennies into groups of ten and then count them.

If a table has “leftovers” (e.g. a group that does not make ten), have students trade coins so that all tables have groups of ten pennies. One table will keep the leftovers.

Ask each table to begin counting their groups of ten. When half the class has counted out their totals, once again ask if anyone wishes to change their estimate, and why.

Allow the students to continue counting until you have the total number of pennies in the jar.

Write the total on the chart paper. Facilitate a discussion about how close

students’ estimates are. Discuss why some estimates were more reasonable than others.

Keep the chart paper for future use. Repeat this activity throughout the unit, using the same jar but using different manipulatives, such as nickels, dimes, or quarters.

Another option is to switch the size of the container rather than the size of the manipulative.

Continue to provide many experiences with estimation, allowing students to share their thinking about what might be a reasonable estimate.

In your discussion, ask students when it might be important to estimate and when it might be important to get an exact count.

through the presentation of key concepts in both concrete and symbolic representations.

Expression is present in the activity through the use of concrete and, when possible, virtual manipulatives.

Engagement is present in the activity through the use of a task that allows for active participation and exploration.

Students will work in pairs for this activity. Distribute pennies and dimes, Math Journals, and Resource Sheet 12: Hundred Chart.

Pose the following word problem to students on chart paper or on the board:

Billy has a total of 78¢ in his piggy bank. All of the coins in his piggy bank are either pennies or dimes. How many of each coin might Billy have in his piggy bank? Is only one answer possible? How do you know?

Allow students about five minutes to get started on their own without any prompts. Students can record each representation in their Math Journals.

As you circulate around the room, encourage students to draw visual representations, use their Hundred Chart, and use the coins. Ask questions such as, “How could you use the coins to get to 78 cents?”

Look for how students organize their coins. Do they make coin sets before determining the

value? Do they count the dimes first, or the pennies?

Allow several more minutes for students to continue to work with their partner or with other students at their table to solve the problem. Encourage students to ask questions of one another.

Bring the class together and ask students to share how they got started on the task. Ask questions, such as: o Can someone tell us what she meant?o So you used all the dimes first. How did

you know you had enough? Why did you use the dimes first instead of the pennies?

o Did anyone use their Hundred Chart to help them? How did it help?

Formative Assessment: Distribute Resource Sheet 15: Billy’s Coins.

Extension Activity:

Distribute Resource Sheet 16: Piggy Bank Recording Sheet.

Allow students time to explore using pennies, dimes, and nickels to find multiple ways to make 92¢. Students can record each representation on Resource Sheet 16. Adjust the amount of money students use as needed.

Allow time for sharing and discussion. Be sure to include in your discussion the two different ways you can write cents (using symbols or

Engagement is present in the activity through the provision of scaffolds that can be gradually released with increasing independence and skills.

Motivation:

Read aloud a book about money to the class, such as Judith Viorst’s Alexander Who Used to Be Rich Last Sunday, or Julie Glass’ A Dollar for Penny.

Allow time for students to respond to the story.

Distribute bags of pennies, nickels, and dimes to each pair of students.

Ask students how to make 25¢. Allow students the opportunity to respond with

ways to make 25¢. List their responses on chart paper. Ask students to remind you of a few different ways to write cents (using a symbol or using words).

Dollar. If no student responds by saying “a quarter,”

introduce the quarter to students as a coin whose value is 25¢.

Show students that two quarters=50¢, three quarters=75¢, and four quarters=one dollar.

Distribute Resource Sheet 17: Dollar Chart. Discuss the chart with students. Ask them what patterns they see and how the chart could help them to count money.

Introduce the game Get to a Dollar (Resource Sheet 18). Model how to play the game with student volunteers. Ask questions as students play, such as, “How much more do we need to get to a quarter? To a dollar?”

If possible, use an interactive white board, document camera, or overhead to model the game.

Although students can get ten dimes to make a dollar, you may want to suggest they attempt to earn four quarters as a variation of the game.

Distribute Resource Sheet 18: Get to a Dollar and number cubes to be used with their bags of coins.

Circulate around the room taking anecdotal notes as students play the game. Look for the various ways students are trading coins. Do they attempt to acquire 4 quarters? How do they trade coins? If a student rolls a seven, do they count out seven pennies or automatically take a nickel and two pennies? Encourage

their limitations.”

students to make trades for higher value coins when possible. The first player to get 4 quarters ($1.00) wins the game.

Ask questions such as:o How much money would you have if you

combined all the coins you have right now?o How many more quarters do you need to

get to a dollar? o How much more money do you have than

your partner? After students have played the game, discuss

students’ responses, asking whether or not it is more efficient to count money beginning with the coins with the greatest value, and why.

Continue to give students experience with exploring coin values. Also give them many experiences making different combinations using dollars once they have become familiar with coins (e.g., How many different ways can you make $16 dollars using $1, $5, and $10 bills?).

Formative Assessment:

Have students complete a Math Journal entry, answering the following: Explain the strategies you used to get to a dollar during the game. An alternative question might be, How would you tell a friend how to trade for a quarter?

The different versions of the game can be placed in a math center so that students can practice the skill of getting to a quarter or getting to a dollar as needed. See the

Expression is present in the activity through the use of concrete and, when possible, virtual manipulatives to play “store” and act out real world scenarios involving money.

Engagement is present in the activity through the provision of varied degrees of freedom for acceptable performance as well as through the differentiation in the degree of difficulty or complexity within which core activities can be completed.

Motivation:

Prepare a separate paper bag or envelope for each of the following amounts: $.45 (9 nickels), $.27 (5 nickels, 2 pennies), and $.75 (2 quarters, 2 dimes, 1 nickel). Do not reveal what is inside each bag or envelope. (Amounts should be modified based on the needs of your students).

Distribute pennies, nickels, dimes, and quarters to each pair of students to use while solving the Money Riddles (Resource Sheet 19).

Show the students the bags or envelopes and tell them that there are coins inside. Explain that students are going to have to guess the total value of the coins inside the bags or

envelopes based on clues to a riddle. (See Resource Sheet 19: Money Riddles).

Reveal one line in a riddle at a time. Once a student makes a guess, they must

explain their reasoning. Some students may disagree with a response. Do not tell students if they are correct or not at this time. It is important that all clues are revealed and that students have time to construct arguments and critique the reasoning of their classmates.

Continue to share money riddles with the class throughout the unit and extending into the school year, if desired. Some students may be able to create their own money riddles after they have experience solving them.

Let’s Go Shopping!

○ Some students may tell you that our money system consists of more than coins. Ask students if they know of any other currency that is used in our money system.

○ Guide students in naming bills and their values. If possible, use play money, pictures, or virtual manipulatives as a visual.

Allow students to create and decorate a change purse/wallet out of construction paper, or give each student a plastic bag with a zipper filled with a variety of bills and coins that total between $5.00 and $10.00). Vary the amount of money students are given based on your

assessment of Activity 1 and Activity 2. Allow students time to count the money in their

change purse/wallet. Display a toy store price list for all students to

see. Ask students to choose one item from the list

that they would purchase. Have students Think-Pair-Share with a partner about which bills and/or coins they would need to use in order to purchase the item.

Have students take out the correct amount of money from their bags and place their bills and/ or coins on their desks.

Allow time for students to share which coins and/or/bills they used for a particular dollar amount. Now encourage students to show another way to purchase this same item using different coins and/or bills.

Have students share with a partner their two different ways of purchasing the item. Partners can check each other for accuracy.

Some questions you can ask students as you circulate around the room: o Suppose I gave you 50 cents for a stamp

worth 45 cents? What change should I receive? (5 cents; 1 nickel or 5 pennies) What is missing when I say 45 + "something" = 50? Can you write an equation”?

o How is making change like counting on? o How can you be sure you have the right

change when you buy something? (You can count on, for example.)



Learning Experience

Distribute Resource Sheet 20: Toy Store Recording Sheet.

Continue to ask students questions as you walk around the room.

Allow time for students to share and discuss their work after they have completed Resource Sheet 20.

You may wish to model how to correctly record a dollar sign ($) next to a number.

Extension Option I:

Have students determine the change they would receive if they paid with $20. Allow students to use a variety of strategies, including counting the money left in their change purse/wallet.

Extension Option II:

This activity can be extended by using a different price list (student or teacher made) and allowing students to purchase more than one item. Money amounts in student change purse/ wallet can be increased.

Extension Option III:

For a challenge, have students sort 15 dimes into four different groups so that each group has a different number of dimes. Students need to determine if zero is a group, and explain why. They will also need to decide if there is more than one answer, and how they



Learning Experience

know they found all possible groupings.

Closure Ask the students to tell you everything they know about our money system. Record student responses on chart paper.

Ask students where they see money used outside of school.

Possible Exit Questions:○ How many different ways can I use coins to

make 87¢?○ How many nickels does it take to make the

same value as two quarters?○ Make a list of all the coins and their values.○ If you dropped a nickel a day into your

piggy bank, how much money would you save in one week? In two?

SMP 3: Construct viable arguments and critique the reasoning of others.

“Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments.”

“Elementary students can construct arguments using concrete referents such as objects, drawings, diagrams, and actions. Such arguments can make sense and be correct, even though they are not generalized or made formal until later grades. Later, students learn to determine domains to which an argument applies. Students at all grades can listen or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments.”
