A knowledge check on one more and one less for Year 1 maths. Pupils start with numbers up to 20, move to a table for numbers like 29, 40, 79 and 90, then solve word problems about stickers and blocks. The answer key makes marking quick. Every question is written to the England National Curriculum objective on identifying one more and one less.

“Given a number, identify one more and one less”
The whole check works this objective, from numbers within 20 up to 90.
