I know a square is a rectangle in which all four sides are of equal length.

Lesson details

Key learning points

  1. The definition of a square is a rectangle with all four sides the same length.
  2. A square has four right angles at its vertices.
  3. A square can rest on a side or a vertex.

Common misconception

Pupils may not realise that squares are rectangles.

Emphasise to pupils that all squares are rectangles but not all rectangles are squares. Rectangles are quadrilaterals with 4 right angles, but squares have 4 sides of equal length.

Keywords

  • Rectangle - A rectangle is a 2D shape with four straight sides and four right angles.

  • Square - A square is a 2D shape with four equal straight sides.

Draw attention to the properties of all rectangles. Then, draw attention to the additional properties of squares. Squares have 4 sides of equal length. They have 4 lines of symmetry. They are regular shapes (any shape where all angles are the same and all sides are the same length).
