Area of compound shapes
Recognise area as additive; find areas of rectilinear figures by decomposing into non-overlapping rectangles and summing their areas
Suggested ages 8–9
Learning journey
Your child is learning to measure the world around them — calculating areas and perimeters, converting between different units like metres and kilometres, and solving time problems using both analogue and digital clocks.
Evidence of understanding
- Decompose an L-shape into two rectangles, find each area, and add them
- Find the area of a floor plan shaped like a T by splitting into rectangles
- Solve: A room is L-shaped (3m×5m plus 2m×4m) — what is the total area?
Assessment prompt
If Area of compound shapes is given an L-shaped room on squared paper, can they split it into two rectangles, find the area of each part, and add them to get the total area?
