# Multiples

## Description

The circle of multiples can be used as a practice game in class. The outside ring are multiples and the inner ring are factors. n represents the other factor. The teacher points to a set of numbers and students replace n with the other factor. For instance, if 72 is chosen, 8 is the factor, and n would be 9.
