SMP Interact is a new generation mathematics course for key stages 3 and 4. It aims to meet teachers' professional needs and provide an enriched learning experience for pupils. This is one of three books for pupils at the end of year 7/beginning of Year 8. There is an associated Teacher's Guide, Practice Book and Resource sheets. The C series leads to the level 5-7 SAT (key stage 4 materials can be drawn on where pupils are working at level 8).
