Add & Subtract 10 | Spider 100 Square Game, Cards & Tutor Guide | Place Value Intervention
A print-and-play 100 square game teaching one idea properly: when you add or subtract 10, the ones digit never changes. 36 cards, recording sheet, 100 squares and a full tutor guide.
A low-prep, no-fuss pack for children who can’t yet add or subtract 10 without counting on in ones. Every calculation stays within 1–100 and crosses no hundreds boundary, so nothing distracts from the single idea being taught: the ones digit stays put, only the tens digit moves.
Designed for 1:1 and small-group intervention as well as whole-class starters. Especially useful for Year 3 and Year 4 children still working below age-related expectations in place value.
