About this worksheet
Kindergarten geometry includes both flat shapes that can be drawn on paper and solid shapes that can be held and turned. Children often memorize a familiar picture instead of noticing defining attributes, so they may reject a triangle that points sideways or call every four-sided figure a square. They may also confuse a flat circle with a solid sphere because both look round in a picture. This worksheet asks children to name shapes, count sides or corners, and decide whether a pictured form is flat or solid. Attribute-based descriptions are especially important: a cube has flat square faces, while a sphere has one curved surface and rolls. Support versions use the most familiar examples. Standard and challenge versions add rectangles, hexagons, cones, and cylinders. Encourage your child to trace flat edges with a finger and imagine whether the solid could roll, stack, or slide before choosing.
What your child will learn
- Name common flat shapes
- Name common solid shapes
- Use sides and corners
- Tell flat from solid
Worked example
A triangle is flat and has 3 straight sides and 3 corners, even when it turns.
Common mistake
Calling a sphere a circle because both appear round from the front.
Helpful hint
Ask whether the shape is flat or has surfaces you could hold.
