This Year 1 addition and subtraction within 20 block helps pupils strengthen calculation strategies through number bonds, making 10, related facts and practical representations. The sequence supports pupils as they move beyond counting small sets and begin using known facts to solve calculations more efficiently.
Pupils explore addition by counting on, making 10 and using number bonds before moving into subtraction that does and does not cross 10. Visual models, part-whole representations and comparison tasks help pupils understand the relationship between addition and subtraction and explain their methods clearly.
Aligned with the White Rose small steps and the Year 1 National Curriculum, this block supports whole-class teaching, guided maths groups and independent fluency practice throughout the Spring term.
