Part To Whole

Purpose:

At the end of this lesson you should be able to explain the difference in part to whole ratios given pattern blocks and an activity sheet.

Directions:

• 1. Work with your table to answer the questions below. Please record your findings.

  2. Each group should send a representative to grab a bag of tangrams for the table.

Part I: Part to Whole

• 1. Trace the hexagon on your paper.

  2. Fill out the blanks in the table below.

Part II: Fractions

• 1. One trapezoid is how much of a hexagon?

  2. One rhombii is how much of a hexagon?

  3. One triangle is how much of a hexagon?

  4. Two triangles are how much of a hexagon?

Part III: Fraction Addition

Directions:

• 1. Given the problems below, sketch a picture of each addition.

  2. Answer the question below. Take a picture of what you’ve done with your shapes.

  3. Choose one of the three questions below, and using a device of your choosing record with one other person explaining:

     1. Introduce you and your group.
