Algebra Detective

Algebra Detective is a five-mission Year 6 (KS2) activity book mapped to the DfE National Curriculum for algebra. Learners express and solve missing-number problems written with letters, substitute values into simple formulae to find exact answers, generate and describe linear number sequences, and find pairs of numbers that satisfy an equation with two unknowns, enumerating the possibilities systematically. 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.
