Lesson details
Key learning points
- Some shapes are better than others to cover the surface and count the area.
- The surface of the shape must be covered with no gaps or overlaps; the unit used must tessellate.
Keywords
Polygon - A two-dimensional shape made up of three or more straight lines.
Tessellate - A shape tessellates if copies of it can fully cover a space without overlapping.
Common misconception
Pupils may well have had recent experience of perimeter. Perimeter and area are easily confused.
Remind pupils that running their finger around a 2D shape will give the perimeter. Running it inside the shape will give the area.
