Number & Place Value Detective KS3 is a five-mission Year 7 (KS3) activity book mapped to the DfE National Curriculum for number. Learners work through the four operations with negative integers, prime factorisation, HCF and LCM, powers and roots including squares, cubes and square and cube roots, the order of operations with BIDMAS, and rounding to decimal places and significant figures with estimation and simple standard form. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
