Lesson: Word Problems: Capacity Mathematics • 3rd Grade

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

Lesson Plan

Students will be able to

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

Lesson Worksheet

Q1:

If 1 liter of water is enough to fill 6 glasses, determine how many glasses can be filled using 3 liters of water.

Q2:

A container contains 200 liters of water. The container’s valve is left open for one minute. The quantity of water in the container is then 150 liters. Use the following number line to find how many liters of water the container has lost.

Q3:

There are 6 liters of water and 200 milliliters of oil in two different containers. If we put them together in a new, bigger container, how many milliliters will we have?
