Subtraction Across a Ten – Year 2 Maths

Subtracting Ones Across a Ten – Differentiated Worksheets (Year 2, White Rose Aligned)

In this small step, learners practise subtracting a 1-digit number from a 2-digit number where the calculation crosses a multiple of 10.

Each subtraction problem guides children through the process using:

• Number lines to support visual understanding.
• Part–whole models to partition the subtracted digit. Learners first step back to the previous ten, then subtract the remainder to find the final answer.
