Day 161: Metric Units of Capacity, Day 2
Focus: The student will estimate and measure the capacity of various containers using
metric units.
Materials: Assorted containers: one set of 4 – 5 containers for each group of 3 – 4
students, water, rice, or sand for pouring into containers, Toss and Talk pages (one per pair)
Activity:
1. Discuss homework from the previous lesson to clarify any questions.
2. Ask each group of students to place their set of containers in order from the one that
has the greatest capacity to the one that has the least capacity. Discuss placement of
the containers with the class.
3. Students will play Toss and Talk with a partner. After students complete the activity,
discuss which capacity estimates were more difficult than others.
4. Students will complete Metric Units of Capacity.
