Description: Get your students writing fully reasoned proofs! In this file there are a selection of common GCSE conjectures that can be proved using algebraic manipulation. First the students do a rough proof (the algebra bit), then they have a go at writing a fully explained proof. This can then be redrafted by a peer and then assessed by a third student.
