Part-part-whole activity sheet
This part-part-whole activity sheet helps Year 1 pupils develop a secure understanding of number bonds and how numbers can be split and combined. Aligned with the White Rose small steps and the National Curriculum, this resource introduces children to the part-whole model in a simple and visual way.
Pupils are asked to complete the part-part-whole diagrams by filling in missing numbers and number sentences. This helps to reinforce the structure of numbers and the relationship between parts and wholes, building fluency with key number facts up to 10 and 20.
The clear layout and repetition of the structure make this worksheet ideal for developing independence and building confidence. It’s perfect for use during the autumn term, particularly when introducing addition and subtraction, and lays strong foundations for later work with bar models and fact families.
Use as part of your daily maths session, in small group support or as an assessment tool to check understanding of number structure and composition.
This activity is part of our complete Year 1 maths worksheets collection, fully aligned with the White Rose small steps and designed to build early fluency and reasoning skills.
