L1 Spring Number Bonds and Facts to 20

This Year 1 maths lesson focuses on helping children understand and apply addition and related subtraction facts within 20 through engaging, hands-on activities. The lesson begins by revisiting number bonds to 10 using Numicon visuals, supporting recall and visual reasoning. Pupils are then introduced to the concept of fact families using part-whole models, learning how three numbers can be used to create two addition and two subtraction facts. Colour coding and clear modelling reinforce the relationship between parts and the whole. During the main activity, children work independently to generate and record fact families in their maths books, strengthening fluency and conceptual understanding. Common misconceptions to address include confusing parts and the whole, reversing subtraction sentences, or forgetting all four related facts. This resource provides a structured, visual, and interactive approach to building strong number sense and confidence in early addition and subtraction.
