Unit Bricks

Unit Bricks is a Grade 5 volume game that uses Lego pieces or similar bricks as unit cubes. Playing cards generate the length and width of a rectangular prism, and students build the solid physically before stating its volume. Points can be earned for constructing the prism correctly and for giving the correct volume.

Use it for partner or small-group work when students are learning volume as the number of unit cubes that fill a rectangular prism. Building the solid before calculating helps connect dimensions with the multiplicative volume relationship.
