Task# Volumes with Fractional Edge Lengths

Illustrative MathematicsVaries

The purpose of this task is to introduce students to fractional units for volume. This task provides opportunities to extend the formula for non-whole number side lengths; practice fraction multiplication and verify the result geometrically; highlight the fact that a volume can be a numerically smaller number than the lengths of its sides. A note about 'plenty of snap cubes' for planning: the largest rectangular solid that a student would build for this task consists of 48 snap cubes. It would be appropriate for students to work in pairs for this task, so you don't necessarily need 48 snap cubes for every student.
