We are starting to see more and more questions at GCSE asking students to spot and correct the mistake made.
Clumsy Clive and Erica’s errors problems by @andylutwyche for are a perfect way to tackle this and I have edited and collated them togther.
“Erica has made some silly mistakes on her homework. Your students’ task is to find the errors, correct them and explain what Erica has done incorrectly. This should generate discussion in class.”
