Kindergarten comparing shapes worksheets

Tap to see another sample sheet.

Comparing shapes worksheets for kindergarten show two shapes side by side, sometimes two flat shapes, sometimes a flat shape and a solid, sometimes two solids, in different sizes and turned different ways. Your child picks the statement that says how they are alike or different: both have three sides, only one has corners, one is flat and one is solid. Six pairs per sheet, and every print draws new pairs.

Each print is a different sheet with its own answer key. You don't need to sign up.

The kind of problems you'll get

Look at each pair. Choose what stays the same when a shape is resized or turned.

  1. How many corners does a triangle have?

    Answer: Three corners.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on a kindergarten sheet

Every version prints on US Letter or A4, with its answer key after the problems.

How to teach this

Ask two questions about each shape before reading the choices: how many sides and corners does it have, and is it flat or solid? Count corners by touching them. Then read the three statements aloud and ask which one is true for both shapes, or true for only one of them. Shapes on the sheet are drawn at different sizes and angles on purpose, so a small tilted triangle still counts as a triangle. With a set of blocks at home, play the same game: pick two, say one way they are alike and one way they differ.

Watch for: Children compare size or position instead of the shape itself, saying the bigger one is different. The choices on the sheet only talk about sides, corners, and flat or solid. Children call a tilted square a diamond and treat it as a different shape. Turn the paper: a square on its corner is still a square. Children think a solid shape and its flat face are the same thing. Hold a real box next to a drawn square and let them feel the difference.

Common questions about kindergarten comparing shapes

Which shapes appear?
Flat shapes like triangles, squares, rectangles, and circles, and solids like cubes, spheres, cones, and cylinders, mixed across the six pairs.
Is this the same as naming shapes?
No. Naming is on our identifying 2D shapes page. This page asks what makes two shapes alike or different, which is the kindergarten standard on analyzing and comparing shapes.
What kinds of statements are the choices?
Things a kindergartner can check by looking: the number of sides or corners, whether a shape has curved parts, and whether it is flat or solid.
Is there writing on this sheet?
No. Your child chooses a statement. Counting sides and corners in writing comes on the first grade sides and vertices page.
