  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?  
 
  1.  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 ? 

 

  1. Handout: Pattern Block Equivalents Practice A
  2.  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?  

          Pattern Block Equivalents Recording Sheet B.

  1. Handout: Pattern Block Equivalents Recording Sheet B 
  2. 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?
