The purpose of this lesson is for students to use their understanding of multiplication and division to estimate products and quotients. This is the first of several lessons where students use multiplication and division to make estimates of large quantities. All of the lessons except the next one use a context of volume.
Students make estimates about the amount of milk consumed by different groups and the number of days it would take these groups to consume 1,000,000 cubic inches of milk. The estimates are structured to build on one another allowing students to use the associative property of multiplication.
- Estimate products and quotients of whole numbers.
- Let's make estimates with big numbers.
