About this worksheet

Composing shapes helps children see geometry as parts that can make a larger whole. First graders use triangles, squares, rectangles, and other shapes to build composite figures, then describe what parts were used. This prepares them for area, fractions, and spatial reasoning later. Children sometimes focus only on the outside outline and forget the smaller shapes that made it.

This worksheet asks them to choose which parts could make a whole, count repeated pieces, and identify a new shape built from smaller ones. Support pages use two simple parts. Standard and challenge pages use three or four pieces while keeping the visuals and language clear. Ask children to trace the outside shape, then trace each inside part separately and explain the build.

What your child will learn

Build a larger shape from smaller shapes
Identify parts inside a composite figure
Count repeated shape pieces

Common Core standard: 1.G.A.2

Worked example
