Lesson 6

Multi-step Conversion Problems: Metric Liquid Volume

Lesson Purpose

The purpose of this lesson is for students to solve conversion problems using metric volume units.

Lesson Narrative

In this lesson, students solve conversion problems involving metric liquid volume measurements. The first activity in this lesson focuses on base-ten structure and conversions and also gives students a chance to work with decimals, fractions, and powers of 10 in exponential form. The second activity is contextual and also involves work with fractions and decimals. It gives students a chance to practice multiplication (by numbers that are not powers of ten) either with whole numbers or a whole number and a decimal depending how they solve the problem.
