    • Let’s solve problems about volume.

Warm-up Notice and Wonder: Radio Flyer

What do you notice? What do you wonder?

Activity 1 Anatomy of an Estimate

  1. What measurements would you take of the wagon to accurately estimate its volume?

  2. What units would you use to measure the wagon? Explain your reasoning.

  3. Record an estimate for the volume of the wagon that is:

    too low

    about right

    too high

  4. What can you use in the picture to refine your estimate?

Activity 2 Estimating the Size of the Radio Flyer

  1. Use the picture of the wagon to make a better estimate of the length, width, and height of the wagon bed.

    Make sure to:

    • explain how you estimated each measurement

    • include how accurate you think each estimate is

  2. Then improve your estimate for the volume of the wagon.
