These Year 4 adding near multiples of 10 worksheets help pupils develop a powerful mental maths strategy for solving addition problems quickly and efficiently.

Children learn how to add the nearest multiple of ten and then adjust the answer, making calculations such as +9, +11, +29, +31, +49 and +51 much easier to solve mentally.

For example:

278 + 9 → add 10 then subtract 1

462 + 29 → add 30 then subtract 1

This strategy strengthens number sense, place value understanding and mental arithmetic fluency, all of which are essential skills in Key Stage 2 mathematics.

The worksheet set includes three differentiated levels to support different learners in the classroom.

Triangles

Focus on adding 9 and 11 to three and four digit numbers.

Circles

Introduce larger near multiples such as 29, 31, 39, 41 and 51.

Squares

Challenge pupils with harder calculations using 49, 51, 59 and 61, encouraging deeper mental maths strategies.

A QR code is included which links to a short instructional video so pupils can review the method independently at home.
