Resources for Teaching Mathematics: 11-14

Colin Foster teaches mathematics at a secondary school in Coventry, UK.

'The problems in this book would enrich the mathematical learning of any class; they are clear and challenging whilst being easily differentiable. Colin Foster has produced a resource that will extend the mathematical learning of any student, helping them to engage with mathematics, instead of just doing mathematics.' James Robinson, Teacher of Mathematics, Ripley St Thomas School, UK
