What to practise

  • Use short daily drills to build automatic retrieval.
  • Mix untimed explanation rounds with faster accuracy rounds.
  • Track weak patterns and revisit them every 2–3 days.

Teaching tips

  • Start with perfect squares only and pair them with their roots.
  • Alternate root and square questions in the same set.
  • Use number line checkpoints to estimate before exact recall.

How to work it out

Step-by-step worked examples to talk through together.

√49 = ?

  1. 1 Ask: what number × itself = 49?
  2. 2 7 × 7 = 49
  3. 3 So √49 = 7

√100 = ?

  1. 1 Ask: what number × itself = 100?
  2. 2 10 × 10 = 100
  3. 3 So √100 = 10

Quick tips for parents & teachers

  • Frame it as a puzzle: "What number times itself gives this answer?"
  • Practise roots alongside squares in the same session — they reinforce each other.
  • Focus only on perfect squares (1–144) at KS2 stage.

Frequently Asked Questions

How often should we practise this topic?

Most learners improve with 10–15 minutes on most school days.

Should we focus only on weak questions?

Prioritise weak areas, but keep a mix of secure questions to maintain confidence.

How do we know when to move on?

Move on when speed and accuracy are both stable across multiple sessions.
