These Year 4 subtracting near multiples of 10 worksheets help pupils develop efficient mental maths strategies by adjusting numbers close to multiples of ten. Instead of using formal written methods, pupils learn to calculate more quickly by subtracting a nearby multiple of 10 and then adjusting the answer. This builds strong number sense and supports the development of flexible mental calculation skills.
For example:
84 − 19
Think: 84 − 20 = 64
Then adjust: 64 + 1 = 65
This approach helps pupils calculate more efficiently and prepares them for more advanced mental maths strategies used later in Key Stage 2.
Differentiation
This resource includes three differentiated worksheets to support a wide range of learners.
Triangles (Support level)
Focus on subtracting numbers such as 9, 11, 8 and 12 from two-digit numbers. Pupils practise adjusting answers by adding or subtracting 1.
Circles (Core level)
Pupils work with numbers close to multiples of 10 such as 18, 19, 21 and 22, applying the strategy with slightly larger adjustments.
Squares (Challenge level)
Includes larger numbers and more challenging calculations, including three-digit numbers and wider adjustments. Pupils apply the strategy independently without prompts.
