Geometric Fractions

Geometric Fractions is a Grade 3 activity that uses geometric shapes to make fraction ideas visible. Students explore how a hexagon can be partitioned into equal parts, then work with a larger hexagon divided into 24 equilateral triangles and describe colored regions as fractions. The geometry gives students a concrete way to reason about parts of a whole and notice equivalent fractional amounts.

This partner activity is useful when you want fraction language tied to an actual model instead of isolated numerator-and-denominator notation. Exchanging completed designs gives students another chance to interpret someone else’s partitioning and reduce fractions when appropriate.
