Year 2 Subtraction: Strategies for Teaching When Kids Get Stuck

Why Year 2 Subtraction Feels Like a Jump

Year 2 marks the point where subtraction stops being just "count back" and becomes a real maths concept. Children have moved from simple problems like 8 − 3 to two-digit work: 23 − 5, and then 23 − 15. That shift—from single figures to the tens place—is exactly where many children hesitate. The good news is that hesitation is completely normal and signals that your child is ready to move deeper, not that something has gone wrong.

In Year 1, most children learned subtraction through physical objects or careful counting. They'd line up 8 counters, remove 3, and count what was left. By Year 2, they need to understand that subtraction works the same way with tens and ones. A child who's confident with 8 − 3 may suddenly doubt themselves with 23 − 15, even though the concept is identical. The jump usually isn't about the maths itself—it's about confidence with larger numbers and the language teachers use ("take away" versus "find the difference" versus "how many left").

The best approach is to slow down and let concrete materials do the explaining. Rushing to abstract sums (just using numbers and symbols) before your child has felt what's happening with tens and ones is the single biggest reason Year 2 subtraction feels stuck.
