"ST (P) Mathematics" offers very useful support to teachers and pupils through the PoS for "Key Stages 3 and 4". Sufficient text is given for pupils to use as a reminder of the main results and methods. Whenever possible, the recommended technique is to give the pupils a starting point from which they can find out mathematical properties for themselves. Each book offers an ample supply of exercises to consolidate work covered by investigation, project, class discussion, class teaching etc. A separate teacher's notes and answers book is published.
