Class 3 Maths — Shapes and symmetry

Count the sides and corners of a shape, name the parts of a solid, find a line of symmetry, and cover a shape with smaller shapes.

Name: ________________________

Before you start

Here is a box drawn as a solid. Find a face, an edge and a corner on it.

  1. 1. A face
  2. 2. An edge
  3. 3. A corner

A corner is the one place where three edges come together at a point.

Take a tile from the tray and lay it on the hexagon. Cover the whole hexagon with one kind of tile, then clear it and try another kind.

  • Triangle, covers 1 triangle
  • Rhombus, covers 2 triangles
  • Half-hexagon, covers 3 triangles
  • Hexagon, covers 6 triangles

Six triangles, three rhombuses or two half-hexagons — every one of them fills the very same space.

  1. 1.How many corners does a square have?

    • a) 5
    • b) 4
    • c) 3
    • d) 6

  2. 2.Which shape has no corners?

    • a) Triangle
    • b) Circle
    • c) Rectangle
    • d) Square

  3. 3.How many sides does a rectangle have?

  4. 4.Match each shape to how many sides it has.

    • Triangle
    • Square
    • Pentagon
    • Hexagon
    • 6
    • 3
    • 4
    • 5

  5. 5.How many faces does a cube have?

  6. 6.Which letter has a line of symmetry straight down the middle?

    • a) A
    • b) F
    • c) P
    • d) J

  7. 7.How many edges does a cube have?

  8. 8.Tap the shape where the line folds it exactly in half.

    Write the number of the part.
