Calculator Crunch supports Key Stage 2-3 transition by providing engaging maths challenges that introduce calculator use as pupils move from Year 6 (P7) to 7 (S1).
Every day for one week in June we post a set of maths challenges that allow students to explore aspects of the maths curriculum and build confidence using calculators as they move from Year 6 (P7) to Year 7 (S1). Perfect for classrooms or at home with parents/carers, the problems aim to promote thinking and reasoning as well as being fun!
Calculator Crunch will run between 15 – 19 June 2026
