What You Learned

After three comes four, then five.
The last number is how many.

For the grown-up

The last number said is how many there are, not the loudest and not the first. This is called cardinality, and it is the single biggest step in early counting.

Every object got exactly one number, so the biggest number reached is how many objects there were. Children who can recite to ten often still cannot answer how many without recounting.

Once they have said five, they know it is five. If they start over to check, they have not made the link yet. Count together again slowly rather than telling them the answer.
