Teacher tips
- • Teach a strategy, not 100 facts. Strategies generalize; rote memorization rarely does.
- • Use timed drills only after fluency is built — speed without strategy creates anxiety.
Parent tips
- • Practice 5 facts a day, 5 days a week. Tiny habits beat marathon sessions.
- • When stuck, ask: 'What strategy could you try?' instead of giving the answer.
If a child is struggling
- • Anxious learners benefit from un-timed practice with manipulatives until accuracy is solid.
