Lesson Plan: Word Problems: Mass Mathematics • 3rd Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve one- and two-step problems with metric units of mass, including mixed measures.
Objectives
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.
Prerequisites
Students should already be familiar with
- recognizing that 1 kilogram equals 1,000 grams,
- converting measures using partitioning,
- adding and subtracting whole numbers up to 1,000,
- the multiplication and division of 2-digit numbers by 1-digit numbers.
