Kindergarten Geometry Worksheets: Count the Sides and Sort Shapes

These Kindergarten geometry worksheets help a child look closely at flat shapes and notice what makes each one different. On the counting pages a child traces the edge of a circle, triangle, square, or rectangle and counts how many sides it has, learning that a triangle has three and a square has four. The sorting pages put a mix of shapes together and ask the child to group them by their number of sides, so shapes that share a feature end up together. Looking carefully, counting sides, and sorting by a single attribute are the first steps in geometry, and they sharpen the same noticing skills a child uses everywhere. The shapes are big and friendly, with plenty of room to trace around the outside, so a child who is just learning the names can take each shape slowly and count the sides out loud.

In this set a child counts the sides of one shape at a time, then sorts a small group by how many sides each has. There is no measuring and no numbers beyond a quick count to three or four — just looking at a shape, running a finger around it, and deciding where it belongs. The pictures are clear and the task is calm.

When your child can count sides and sort shapes with ease, you can print more of these shape worksheets as a PDF and keep exploring on paper. Everything is free, with no sign-up and no account, and there are no timers or scores, so a child can trace each shape at their own pace. A mix-up is just a chance to count the sides again. When kindergarten shapes feel easy, the Grade 2 geometry worksheets look at faces, edges, and corners, and you can browse the full set of printable geometry worksheets any time.
