Videos and lessons to help Grade 3 students learn to measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

### Masses

3 MD 2 Lesson 1

In this lesson, you will learn how to measure masses of objects.

The mass is the amount of matter in an object. It is usually measured in grams (g) and kilograms(kg).

We can use benchmarks to estimate mass.

A gram is about the mass of a paper clip.

A kilogram is about the mass of 1000 paper clips.

We can use tools like a scale to find mass.

### Liquid Volumes

3 MD 2

In this lesson, you will learn how to measure liquid volume of objects.

Liquid volume is how much liquid something can hold. It is usually measured in milliliters (ml) or liters (l)

We can use benchmarks to estimate liquid volume.

Water bottles, smaller milk containers are about 1 liter.

Large soda is about 2 liters.

A milliliter is a little drop.

We can use tools like a graduated cylinder to measure liquid volume.

**Liquid Volumes and Masses**

Estimating liquid volume and masses 3MD.2

Volume - the amount of space something takes up.

Mass - the amount of matter something has.

**Problem solving with mass and volume 3MD.2**

Examples:

1. Bob has 30 students in his class. He is bringing in juice. About how much should he bring?

2. Billy had 378 grams of soil. He needs 515 grams of soil for his garden. How many more grams does he still need?

3. Bob drinks 2 liters of water each day. How many liters of water does he drink in 9 days?

The Common Core State Standards (CCSS) videos are designed to support states, schools, and teachers in the implementation of the CCSS. Each video is an audiovisual resource that focuses on one or more specific standards and usually includes examples/illustrations geared to enhancing understanding. The intent of each content-focused video is to clarify the meaning of the individual standard rather than to be a guide on how to teach each standard although the examples can be adapted for instructional use.

You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics. Try the given examples, or type in your own problem and check your answer with the step-by-step explanations.
