Number Detective Activity Book

Number Detective Activity Book is a five-mission Years 1–2 maths activity book mapped to the DfE National Curriculum for addition and subtraction. Children secure number bonds to 10 and 20, add and subtract one- and two-digit numbers, solve missing-number sentences, and tackle one-step word problems. 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.
