Lesson details
Key learning points
- Area and perimeter are calculated from the side lengths of 2D shapes.
- Area is measured in square units.
- Perimeter is measured in units of length.
Keywords
Area - Area is the measurement of a flat surface and measures 2D space.
Perimeter - The distance around a 2D shape is its perimeter.
Common misconception
Area and perimeter are easily confused. In this lesson, both concepts are explored, often at the same time.
Use your knowledge of the pupils' attainment (including using the Starter Quiz) to see which pupils are confusing the terms. All pupils will benefit from access to a working wall which gives a clear reminder of which is which.
