Instructions

Play through this interactive game to learn about Volume of Right Rectangular Prisms. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

A unit of volume, a cube with a side length of 1 unit, is called a unit cube.(ES)

Understand that multiplying the length times the width of a right rectangular prism can be viewed as determining how many cubes would be in each layer if the prism were packed with or built up from unit cubes. The height of the prism tells how many layers would fit in the prism.

Build right rectangular prisms and count the cubes and see that they are composed of layers of cubes.

Mentally decompose and recompose a right rectangular prism built from cubes into layers, each of which is composed of rows and columns.

Solve real world and mathematical problems using the formula for volume which can be derived as length times width times height, or the area of the base times the height (V = l x w x h or V = B x h).

Side lengths are whole numbers.

Recognize volume as an attribute of a solid figure.

Pack cubes (without gaps) into right rectangular prisms from cubes and count the cubes to determine the volume.

Use unit cubes as a basis for students understanding of volume as a measurable attribute.

Volume is consists of layers of measurable units.

Discussion Questions

Before the Game

What real-life objects are rectangular prisms? What are different ways to find volume using unit cubes? If area is for 2 dimensional figures and volume is for 3 dimensional figures, how do you think area and volume are related?

After the Game

How were you able to use the unit cubes to determine the volume of the objects in order to unlock the gates? What is the unit of volume used in the game? What formulas did you learn to calculate the volume of a rectangular prism?
