For maths today I would like you to play a fun game called Hidden Treasure.
You will need some jewels (or something else you have that you can use as 'treasure') and 3 bowls/cups that are big enough to fit over your 'treasure'.
Put three bowls over one, two and three jewels.
Quickly lift and replace one bowl and challenge children to say how many there are.
Swap the bowls around rapidly for a minute.
When you stop, can they point to the bowl with three?
Lift the bowl and see if children can instantly say whether they are right.
How did you know there were three?
Challenge- how can you arrange 4 and 5 so you can recognise immediately?
