Overview
Fraction squares provide an area-based model for children to learn about fractions. They can be used for fraction comparisons, finding equivalent fractions, and various forms of fraction arithmetic (addition, subtraction, multiplication, division).

Examples of Use
Comparing Fractions
Fraction squares provide a simple means of comparing fractions. In the example below, 3/4 and 4/5 are being compared. Such tasks give students an internal sense of the size of fractional parts and how they compare to each other. In this case, a child can know that 4/5 is larger because 1/5 (the part missing for fifths) is smaller than 1/4 (the part missing for fourths).
