I put together the following as an activity for a low-attaining year 8 class coming to grips with area. They’ve done area of rectangles and triangles last lesson and so I’m trying to link it to real world contexts this lesson.

The idea is they cut out the shape for which they need to find the area, they then choose a covering for it from the second sheet and cut that out too. They stick both next to each other in their book and then calculate the area and then the total cost of the covering required. I’ve kept it all per sq m to begin with. With the cans of paint they’ll need to calculate how many cans to buy given the coverage of each can. The final slabs choice requires more thought as they are a bulk-buy and not in sq m units. It’s also a compound shape.
