A practical Year 4 perimeter and area 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 calculate perimeter and compare areas.” Ask your child to explain any words they already know.
2
Model one example together: Rectangle 9 cm by 4 cm. Perimeter?
3
Let your child try two questions independently: Rectangle 9 cm by 4 cm. Area? / Square side 7 cm. Perimeter?
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 perimeter and area in one sentence.

Helpful prompts
Ask the learner to show working or quote evidence only where the task requires it.
Use the answer guide to identify the exact misconception rather than asking for unnecessary extra writing.
For extended English tasks, quality and accuracy matter more than length.
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.
