- Amount: A quantity of something.
- How many: You ask how many when you want to know the number in a set or group.
Common Mistakes To Avoid

Know subitising is recognising how many things are in a group without having to count them one by one. See regular arrangements of small quantities e.g. a die face.
2. Use this key word in a maths sentence and explain it clearly. 'Subitise'
To subitise means instantly recognizing the number of objects in a small group, without counting. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Reliance on counting strategies. Not recognising combinations of smaller quantities within 5. Correction: Play games involving dice outside of the lesson to encourage subitising of more familiar arrangements. Then, look at those unfamiliar, such as the way a group of cubes appears when dropped onto a table. 'I can see ___ and ___. I can see ___!'.
