KS1 Subtraction Practice for Years 1–2
Subtraction has more than one useful meaning. Children use it to take an amount away, to find how much smaller one quantity is than another, and to work backwards from a whole to a missing part.
What to understand in this topic
- represent taking away from a starting amount
- find the difference between two quantities
- count back accurately when that method is efficient
- use addition facts to check a subtraction answer
A common point of confusion
A common difficulty is assuming every subtraction problem means physically crossing items out. “What is the difference between 9 and 6?” is better understood as comparing the two amounts, even though the calculation is still 9 − 6.
Try a quick example
Question: There are 11 apples and 4 are used. How many remain?
Answer: 7
Start with 11 and subtract 4. The remaining quantity is 7.

What a parent can try at home
Make two towers of building blocks, one with 9 blocks and one with 6. Ask how many blocks would need to be added to the shorter tower to make them equal.
How NexEdu practises this
NexEdu can practise subtraction facts, missing numbers and short word problems. Counters and number lines can still help when a child needs a visible model rather than an abstract calculation.
NexEdu provides guided questions throughout the child’s available daily tutoring time. A hint can follow an incorrect answer, and two consecutive incorrect answers trigger a brief reteach before practice continues. Same-day topic progress can resume where the child left off.
