Section B: Practice Problems Measure by Iterating up to 120 Length Units

Problem 1 (Lesson 5)

Use connecting cubes to measure the length of each rectangle.

  1. Rectangle.
  2. Rectangle.
  3. Rectangle.

Problem 2 (Lesson 6)

  1. Jada says the rectangle is 5 paper clips long.

    Measure an object. 5 paper clips above a rectangle. Small space between each paper clip. 

    Do you agree with Jada? Why or why not?

  2. Do you think the rectangle is less than 5 paper clips long, 5 paper clips long, or more than 5 paper clips long?
    Show your thinking using drawings, number or words.

Problem 3 (Lesson 7)

Jada and Han measure the rectangle.

Objects. Top, 3 paper clips lined up end to end. Middle, rectangle. Bottom, 8 connecting cubes. Objects in each row start and end at the same place.

Jada says the rectangle is 3 long.

Han says that it is 8 long.

Explain how both Jada and Han can be correct.

Problem 4 (Lesson 9)

Lin measured the length of a table top using these cubes.

Connecting cubes. 10 towers of 10 cubes. 7 single cubes.

What is the length of the table top?
Show your thinking using drawings, numbers, or words.
