Kindergarten identifying 3d shapes worksheets

Kindergarten 3D shape worksheets mix two kinds of problems: most show a solid (cube, sphere, cone, or cylinder) with three names to circle, and the rest show a shape and ask whether it is flat or solid.

The kind of problems you'll get

Circle the name of each solid.

  1. Circle the name of the solid.

    Answer: cube

  2. Circle the name of the solid.
  3. Is this shape flat or solid?

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 each sheet

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Grab real objects first (a ball, a can, a party hat, a tissue box) and let your child match each drawing to something they can hold. For the flat-or-solid items, ask, could it hold cereal, or would everything fall off? Solids take up space; flat shapes just cover it.

Watch for: Kids call every box a cube. A cube's faces are all squares, so a longer box is a rectangular prism, not a cube. Kids name solids by their flat faces, calling a cylinder a circle. The circle is just one face of it; the whole solid is a cylinder.

Common questions about identifying 3d shapes

What does flat or solid mean on these sheets?
Flat shapes like circles and squares lie on the paper; solid shapes like balls and boxes take up space. Some kindergarten problems just ask your child to circle which kind the picture shows.
Which solids does kindergarten cover?
Cube, sphere, cone, and cylinder: the four named in the kindergarten standards. Each drawing comes with three names, and your child circles the right one.
