Lesson: Word Problems: Mass Mathematics • 3rd Grade

In this lesson, we will learn how to solve one- and two-step problems with metric units of mass working with whole number units and mixed measures.

Lesson Plan

Students will be able to

model word problems about mass and determine which operation to use,
solve one-step word problems with mixed measures,
solve two-step word problems with mixed measures,
use known mass conversions to rename measures when solving problems.
