Lesson details
Key learning points
- If you have the same number of squares, the area will be the same however they are arranged.
- There must be no gaps or overlaps between the shapes for the area to be the same.
Keywords
Area - The measurement of a flat surface. It measures a 2D space.
Rectilinear - Rectilnear shapes are 2D polygons composed of one or more rectangles.
Common misconception
Two shapes cannot have the same area if they look different.
Use square sticky notes. Pupils can then move the shapes around to prove that two shapes can have the same area but look different.
