How Many in Total?
Cardinality principle: the last number said when counting a set tells how many objects are in the set, regardless of arrangement or order counted
Suggested ages 4–6
Evidence of understanding
- After counting a set, answer 'how many?' with the last number stated
- Understand that rearranging objects does not change the count
- Understand that counting in a different order gives the same total
Assessment prompt
If How Many in Total? counts out 7 toy cars and you ask "so how many cars are there?", do they say "7" straight away — or do they count them all again from the start?
