# Section B: Practice Problems Weight and Liquid Volume

## Section Summary

Details

In this section, we learned how to measure and estimate weight in grams and kilograms.

This paper clip weighs about 1 gram.

This basket of apples weighs about 1 kilogram.

We also learned how to measure and estimate liquid volume in liters.

## Problem 1 (Lesson 6)

1. Circle the items that might weigh about 1 gram.

1. a piece of gum

2. a turtle

3. a dollar bill

4. a chair

5. a pen

2. Circle the items that might weigh about 1 kilogram.

1. a giant tortoise

2. a pencil

3. a pineapple

4. a large book

5. a full lunchbox

## Problem 2 (Lesson 7)

For each item, decide whether it holds more than a liter, less than a liter, or about a liter.

1. a bathtub

2. a cup

3. a swimming pool

4. a small pot for a plant

## Problem 3 (Lesson 8)

1. What is the volume of liquid shown in the container?

2. Shade the image of the empty container to show  liters of water.

## Problem 4 (Exploration)

Kiran thinks that weight and volume go together. The bigger something is, the heavier it is and the heavier something is the bigger it is. Do you agree with Kiran? Give some examples to explain your thinking.

## Problem 5 (Exploration)

You have a 3 liter jug of water and a 5 liter jug of water. How can you measure out 4 liters of water precisely using these two jugs?
