I just developed this resource aimed at Higher GCSE students, where pupils have to use their knowledge of area formulae of various 2D shapes, to find the shaded area. It is not as straightforward as similar tasks I have seen before. Students must use clues to work out facts about some of the shapes before they can find their areas. I hope you enjoy it. My Y10 set 2 are about to go head to head with sets 1 and 3 this afternoon to be the first class to get the answer. However, we are going to award points depending on accuracy. The instruction at the start of the lesson will be to find the area to an appropriate degree of accuracy. An answer correct to 5 s.f. will ultimately earn more points than an answer correct to 1 s.f.

Enjoy!
