High-engagement Four in a Row strategy game – student choice + built-in challenge! Students pick any question, solve it, claim the square and compete to get four in a row while blocking their opponent. Natural differentiation: they start easy and push to harder questions. Also works perfectly as a self-checking independent worksheet. 36 questions on writing repeated multiplication in index form. Ideal KS3 Year 7–8 starter, plenary, pair work or revision. Laminate for reuse.
