Lesson details
Key learning points
- The definition of a square is a rectangle with all four sides the same length.
- A square has four right angles at its vertices.
- A square can rest on a side or a vertex.
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.
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.
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).
