These Year 5 subtracting near multiples of 10 worksheets help pupils develop efficient mental maths strategies by adjusting numbers close to multiples of ten or twenty.
Instead of relying on formal written methods, pupils learn to calculate more quickly by subtracting a nearby multiple of 10 or 20 and then adjusting the answer. This approach strengthens number sense and encourages flexible thinking when working with larger numbers.
For example:
286 − 17
Think: 286 − 20 = 266
Then adjust: 266 + 3 = 269
This strategy helps pupils perform calculations more efficiently and prepares them for more advanced mental maths used later in Key Stage 2 and beyond.
The worksheets include three levels of differentiation to support a wide range of learners and allow teachers to target support and challenge effectively.
Differentiation
Triangles (Support Level)
Pupils practise subtracting numbers such as 9, 11, 8 and 12 from two- and three-digit numbers. The focus is on adjusting answers by adding or subtracting 1 or 2 after subtracting the nearest multiple of 10.
Circles (Core Level)
Pupils work with larger numbers and begin subtracting values close to multiples of 10 and 20, such as 19, 21, 18 and 22. This encourages deeper understanding of mental adjustment strategies.
Squares (Challenge Level)
More challenging calculations include larger three-digit numbers and adjustments of 1, 2 or 3 when subtracting numbers close to multiples of 10 or 20. This level builds confidence and flexibility with mental subtraction.
