About Before & After

Before & After builds number sense. A number appears with an arrow; tap the number that comes just before or just after it. Start with numbers up to 30, go up to 200, then try counting in twos, fives and tens.

How to play

1. Choose a level.
2. Read the number and the arrow — after (➡️) or before (⬅️).
3. Tap the correct number (or press 1–4).
4. Ten questions per round.

Tips

For 'before', count up to the number and then step back one — it's easier than counting backwards from scratch.
