Year 4 Addition and Subtraction Teaching Slides
These Year 4 addition and subtraction teaching slides support a sequence of lessons focused on applying efficient calculation strategies, estimating answers and checking calculations using inverse operations. The slides guide pupils through deciding which subtraction method is most appropriate, rather than relying on written column methods in every situation.
Early slides revisit subtracting using formal written methods before introducing finding the difference using number lines. Pupils explore when counting on or counting back is more efficient, particularly when numbers are close together. The concept of constant difference is developed, showing how adding to or subtracting from both numbers can simplify calculations while keeping the difference the same.
The presentation also includes a full sequence on estimating answers to addition and subtraction calculations. Pupils practise rounding to the nearest 10, 100 and 1,000 to generate sensible estimates, compare estimates with exact answers and decide which level of rounding is most appropriate in different contexts, including word problems.
Later slides focus on checking answers using estimation and inverse operations. Pupils revisit the relationship between addition and subtraction, use inverse calculations to check their work and explore the commutative property of addition. Key questions are built into the slides to prompt discussion, reasoning and explanation throughout the lessons.
The slides are designed to support clear teacher modelling, whole-class discussion and guided practice, and align with the Year 4 National Curriculum and the White Rose Maths small-step progression for addition and subtraction.
