A practical Year 1 one more and one less parent guide with a 10–15 minute home-learning routine, prompts and answer guidance.
Home learning
A 10–15 minutes practice routine
You do not need to recreate a classroom lesson. A short routine that mixes explanation, one modelled example and independent recall is enough for useful home practice.
1
Start with the learning goal: “I can find the number just before and just after.” Ask your child to explain any words they already know.
2
Model one example together: One more than 7 is __.
3
Let your child try two questions independently: One less than 12 is __. / What number comes before 20?
4
Ask “How do you know?” or “Which clue/fact helped?” so the child explains the method rather than only giving an answer.
5
Finish with a quick retrieval check: Explain one more and one less in one sentence.
Support without giving the answer
Helpful prompts
Read instructions aloud if needed. Let the child use counters, drawings, fingers or oral answers where appropriate.
Keep practice short and practical. Do not require written explanations unless the English task is specifically about writing.
If the child is stuck, model one similar example and then return to the question.
Ask “What do you notice?” before explaining the method.
If your child is stuck, reduce the numbers/text complexity before returning to the original question.
