Six shape ideas

Shapes are flat or solid. Tap each term to see what it means, with an everyday example.

The three big ideas

  • A flat shape can be drawn on paper. It has sides and corners but no thickness.
  • A triangle has 3 sides and 3 corners; a square and a rectangle each have 4 sides and 4 corners.
  • A circle is special — it is round, with no straight sides and no corners.

Worked example. A kite-shaped patang has 4 straight sides. How many corners does it have?

A shape with 4 straight sides has a corner where each pair of sides meets — so the patang has 4 corners.

  • A solid shape takes up space — you can pick it up. A dice is a cube, a matchbox is a cuboid.
  • A ball is a sphere, a party cap is a cone, a biscuit tin is a cylinder.
  • Solids have faces (flat surfaces), edges (where faces meet) and corners (where edges meet).

Worked example. A matchbox is a cuboid. How many flat faces does it have?

A cuboid has a top and bottom, a front and back, and two sides — that is 6 flat faces.

  • Round solids (ball, tin) can roll. Box-shaped solids only slide.
  • When shapes fit together with no gaps, we call it tiling — squares tile a floor neatly.
  • Circles do not tile — they leave little gaps between them.

Worked example. Will square tiles or round coins cover a floor with no gaps?

Squares fit edge to edge with no gaps, so square tiles cover the floor; round coins leave gaps.

Common mix-up: A ball is a sphere, not a circle. A circle is flat (on paper); a sphere is solid (you can hold it).

Where you’ll meet it

Shapes around the house

Buildings and rooms

Doors and windows are rectangles, a clock face is a circle, a roof can be a triangle. Builders pick shapes for a reason.

Toys and games

Dice are cubes, marbles are spheres, ice-cream cones are cones. Spotting solids makes you a shape detective.

Floors and walls

Tiles are squares or hexagons so they fit with no gaps. That is tiling — shapes packed perfectly together.

Hi! Ask me about flat shapes, solid shapes, corners, faces, or what can roll.
