Part-whole model addition and subtraction within 10 worksheets
Use these part-whole model addition and subtraction within 10 worksheets to help Year 1 pupils explore the relationship between addition and subtraction facts. Linked to the White Rose small steps and National Curriculum, these worksheets focus on using part-whole models to develop fluency and reasoning skills within numbers up to 10.
The activities guide children through solving missing number problems, completing part-whole diagrams, and understanding the inverse relationship between addition and subtraction. This supports a deeper understanding of number structure and helps pupils make connections between different representations.
Each worksheet is clearly laid out with accessible visual models and a mix of question types, including number sentences and part-whole diagrams. Differentiated versions are included to support varying levels of understanding, making it easy to adapt for whole-class work or targeted intervention.
These worksheets can be used independently or as part of a lesson sequence on number bonds and early calculation. They’re ideal for daily fluency sessions, quick assessments or recap activities throughout the term.
This resource is part of our full collection of Year 1 maths worksheets, aligned with the White Rose small steps and our full Maths Masters scheme.
