Part of the ST(P) graded series in mathematics, this book follows 1A and is intended to complete the coverage of Level 5 of the National Curriculum, most of Level 6 and about half of Level 7. Some of the work goes beyond Level 7, offering flexibility for those teachers who prefer to do the work at this stage in preparation for the tests at Key Stages 3 and 4. The exercises are divided into three types of question. The first kind is aimed at helping pupils to understand the work, the second is for quicker workers, for extra practice or for later revision and the third is slightly more difficult, for those who have managed the first type fairly easily.
