## Lesson 6 - Measuring and Comparing Volume

To encourage your child to have fun on the Web while learning about Measuring and Comparing Volume, here are some games and interactive activities they can do on their own or in pairs.

### Goal

Estimate, measure, and compare volume using cubic centimeters.

### Builds Upon

Student Book pages 314-315

### Instructions for Use

Volume Using Cubic Centimetre Blocks lets your child measure and compare volumes using cubic centimetre blocks.

To use Volume Using Cubic Centimetre Blocks, have your child read and follow the step-by-step questions. Click on the "Let's Practice!" link at the bottom of the Web page to practice measuring and comparing volumes using cubic centimetre blocks.

Practice Volume Using Cubic Centimetre Blocks lets your child find the cubic measure of each object by counting the cubic centimetre blocks.

To use Practice Volume Using Cubic Centimetre Blocks, have your child answer the questions from the pull-down menus. Click the 'Submit' button to see the score.

Cubes lets your child determine the volume of a box by manipulating and enumerating unit cubes, rows of unit cubes, or layers of unit cubes.

To use Cubes, click on one of the three buttons with the picture of a shape to add a cube, add a row of cubes, or add a layer of cubes inside of the box. To undo a choice, click the 'Remove Last' button. To start over, press the 'Clear ' button. To adjust the size of the box by changing the width, depths, or height fields, click on the 'Change Box' button. To fold the sides of the box in position, click on a side; click again to fold the side to its original position.

Surface Area and Volume prompts your child to investigate 3-D shapes to measure volume.

To use Surface Area and Volume, click on the object and drag the left mouse button to rotate it. Adjust the width, depth, and height sliders to change the volume and surface area of the prism.   Use the 'View' buttons to see the prism from different axis. Use the pull-down menu to choose the type of polyhedron to display.
