Factorising - Double Bracket

A series of lessons (2-3) on factorising quadratics into double brackets. There is a recap on factorising into single brackets and then a RAG task on factorising into double brackets in various forms. There is also a separate RAG task on the difference of two squares. All tasks lead into problem solving questions aswell as allowing all pupils simplify algebraic fractions by factorising.
All tasks are differentiated to at least 3 levels. There are reasoning and problem solving tasks which are suitable for the new curriculum. All tasks have solutions so that it is easy for the pupils to mark their work. This has been used and allowed pupils to master the skill and for the more able to develop their understanding
