Learn the math: Composing Wholes with Unit Fractions

A unit fraction is one equal part of a whole. The denominator tells how many such parts make one whole.

A worked example

Four pieces of size 1/4 make 4/4 = 1. Eight pieces make 8/4 = 2 wholes.

Keep in mind while you play

Count the modules and relate them to the number required for each complete ring.
