This Year 2 Adding Near Multiples of 10 worksheet set helps children develop efficient mental maths strategies when adding numbers such as +9, +11, +19 and +21.
Instead of calculating directly, pupils are encouraged to use a powerful strategy: add the nearest multiple of 10 first and then adjust the answer. For example, when solving 34 + 9, children can think 34 + 10 = 44, then subtract 1.
This method strengthens number sense, improves calculation fluency and prepares pupils for more advanced mental arithmetic.
The worksheets are clearly differentiated into three levels, making them perfect for classroom teaching, homework or targeted support.
Included in this resource
• Triangles – foundation level focusing on +9 and +11
• Circles – middle level including +19, +21 and other near multiples
• Squares – more challenging problems requiring flexible mental strategies
• Full answer sheets included
