6-8 Interventionists Training Session 3

November 12, 2013

Today’s Learning Target & Success Criteria

We are learning to …• Understand the meaning and importance of

“explicit and systematic instruction.”We will be successful when we can…• Identify what “systematic and explicit

instruction” looks like and sounds like during small group intervention for fraction equivalence.

A Research Based Approach to Intervention

Emerging Key Research Themes• Increased instructional time in addition to core

mathematics taught in Tier 1.• Small-group instruction utilized in all tiers• Explicit methods of instruction (e.g., CRA, Talk Moves)• Use of concrete and pictorial representations to facilitate

conceptual understanding• Strategy instruction for problem solving (e.g., Think Aloud)• Focus on problem solving skills (not just computation)• Careful alignment of instruction and content in Tier 1 and

Tier 2 • Screening and progress monitoring to target deficit areas

Explicit and Systematic Instruction

Look back at your notes from our last meeting and gather 2 ideas to share regarding how you might explain “explicit and systematic instruction.”

Jot those ideas down on a notecard.

• Engaging tasks and clear problem-solving models (e.g., tape diagrams)

• Time for students to think • Teacher modeling followed by guided and

independent practice using carefully orchestrated examples and sequences of examples.

• Corrective feedback as needed• Opportunities for students to participate and hear

teachers thinking aloud• Concrete objects to understand abstract

representations and notation (CRA)

Explicit and Systematic Instruction

Hiking Around The Lake

Jason hiked 3/4 of the way around Devil’s Lake. Jenny hiked 3/5 of the way around the lake. Who hiked the farthest?

Solve this task as a student in your intervention group might.

Hiking Around The Lake

• What’s the mathematics targeted in this task?• Move the task through the 5 modes of

representation.•In what ways do these translations from one representation to the next surface the mathematics?

•How might we make the connections between representations explicit?

Give a context: tell a story

Explain orally and/or in writing

Use concrete models:manipulatives

The Garden

Jim and Sarah each have a garden. The gardens are the same size. 5/6 of Jim’s garden is planted with corn. 7/8 of Sarah’s garden is planted with corn. Who has planted more corn in their garden?

Work this through with a partner. How might you approach this in your intervention group “systematically and explicitly.”

Building on An Understanding of Fraction as Number

Fraction Equivalence

Where does the difficulty with fractions begin? Research says…

• Premature experience with formal procedures may lead to symbolic knowledge that is not based on understanding impeding students’ number and operation sense.

• Some students “have a continuing interference from their knowledge of whole numbers.”

• Difficulty reasoning with fraction symbols as quantities.• Knowledge that is dependent primarily upon memory, rather

than anchored with a deeper understanding of foundational concepts, contributes to incorrect use and misunderstanding of formal algorithms.

The Importance of Fraction As Number

“Students who really do not understand what a fraction means will have a hard time finding another fraction equivalent to it.” (Bezuk & Bieck, 1993, p. 123)

Making Fraction Strips

White: whole

Green: halves, fourths, eighths

Yellow: thirds, sixths, ninths

?: twelfthsNote relationships among

the fractions as you fold.

Remember – no labels.

• Place the whole fraction strip that represents 0 to 1 on a sheet of paper. Draw a line labeling 0 and 1.

• Lay out your fraction strips, one at a time, and make a tally mark on the line you drew. Write the fractions below the tally mark.

• Look for patterns to help you decide if two fractions are equivalent.

Equivalency

Which fractions are equivalent? How do you know?

Understanding the Concept: Equivalent Fractions

Two properties are central to the equivalence of fractions• Saying that two fractions are equivalent is

saying that the two fractions are different names (symbols) for the same number.

• There are an infinite number of different names for a give fraction.

How might your intervention students approach this task?

There are some candies in a dish.

2/5 of the candies are chocolate3/10 of the candies are peppermint

Are there more chocolate candies or more peppermint candies?

Move this task through

the 5 Modes of

Representation.

What does this model highlight about this student’s understanding about fractions?

Zero in on your targeted skill of equivalence:

What questions might you ask this student to help her see the relationshipbetween fifths and tenths?

Looking at Figure 1 and Figure 2what relationships is this student ready to see that will help you hit the target of equivalence?

Figure 1

Figure 2

How can the patterns students find in visual models lead to an efficient procedure for finding equivalent fractions?

“Researchers suggest developing the connections between the concept and the procedure through interaction with models and manipulatives. Using the models and manipulatives helps to reveal patterns and relationships built on an awareness of the connections between the size and number of equal parts in a whole.” p. 136 A Focus on Fractions

Missing Number Equivalencies

Van de Walle, p. 223 Activity 12.15

Find the missing number.Explain your solution.

1st : Use a visual fraction model.2nd : Use numbers.3rd : Describe how the numbers apply tothe models using accurate math language. Practice the language from the previous activity.

Systematically Moving Toward Fluency

Researchers have found that instruction which helps students to move flexibly between representations (spoken and written words (two-fifths), pictorial representations, manipulatives, contexts, and symbols) and within representations (e.g., ¾ =6/8) will help students move toward equivalence reasoning that becomes free of the need to model. (Post, Wachsmuth, Lesh, & Behr, 1985).

Understanding equivalence and have an efficient procedure to find equivalent fractions are critical to success with problems involving comparing, ordering, and operating with fractions.
