Lesson 1 Day1: Fraction Layer Book
Lesson 1: Day 2 (Equivalent Fractions)
Day 3 Equivalent fractions with Pattern Blocks
Imagine that you are holding a bag with the following pattern blocks within it:
10 yellow hexagons, 10 red trapezoids, 10 blue rhombi, and 10 green triangles in a plastic zip bag.

- If a hexagon is 1 whole, what part of the whole is a trapezoid? How do you know?
- Are there other blocks you can use to show the hexagon with different fractional parts?
- Pattern Block Equivalents Recording Sheet A
- What fractional part of the yellow hexagon is represented by the red trapezoid?
- What fractional part of the blue rhombus is the green triangle?
- How can both the red trapezoid and the blue rhombus be equivalent to ?
- What fractional part of the red trapezoid is the green triangle?
- What fractional part of the yellow hexagon is the blue rhombus?
- How can both the green triangle and the blue rhombus be equivalent to ?
- Handout: Pattern Block Equivalents Practice A
- replicate the model using your selection of Pattern Blocks.
- If these hexagons represent 1 whole, what part of the whole is a trapezoid? How do you know?
- Are there other blocks you can use to show the hexagon with different fractional parts?

- Handout: Pattern Block Equivalents Recording Sheet B
- Use the other pattern blocks from your selection of blocks to find other ways to show the 2 hexagons.
- What fractional part of the whole (two hexagons) did we say the red trapezoid was?
- When you shaded in each model to show one-half, how many trapezoids did you shade?
- Out of how many total trapezoids?
- What fraction could you use to represent the two out of four trapezoids shaded?
- How many rhombi did you shade to show one-half?
- Out of how many total rhombi?
- What fraction could you use to represent the three out of six rhombi shaded?
- How about the triangles? When you shaded one-half of the model, how many triangles did you shade?
- Out of how many total triangles?
- In Practice A, one red trapezoid is of the yellow hexagon and 2 red trapezoids are equal or equivalent to one whole hexagon.
- In Practice B, one red trapezoid is of the 2 yellow hexagons or the whole and 4 red trapezoids are equal or equivalent to one whole.
- Is the fractional value of the red trapezoid from Practice A equivalent to the fractional value of the red trapezoid from Practice B? Explain. Yes or No - explain.
- How does the red trapezoid from Practice A compare to the red trapezoid from Practice B?
