Lesson 8 Estimate and Measure Liquid Volume

    • Let’s measure and estimate liquid volume.

Warm-up Number Talk: Divide by 3

Find the value of each expression mentally.

Activity 1 Estimate Liquid Volume

  1. Clare says the bathtub holds about 2 liters.

    Jada says the bathtub holds about 20 liters.

    Kiran says the bathtub holds about 200 liters.

    A bathroom.

  2. Would the bucket and the bottle hold 2 liters, 20 liters, or 200 liters? Explain how you know.

    A bucket.
    Bottle.

  3. Match the containers to the number of liters they could hold. Be ready to explain your reasoning.
