The lesson

A number can be written two ways. You write 12 with digits. You write twelve with letters. Both mean the same amount.

Tap each star and count out loud.
Twelve stars. The word twelve means the number 12.
Try it together

Leo gets a birthday card. It says the word nine. Leo reads the letters n-i-n-e. He knows that word means 9. Today Leo turns 9.

Good to know

Two words do not follow the pattern: eleven and twelve. Learn them by heart. Most other words end in teen, like thirteen and fourteen.

Every number 1 to 20 has a word to read and write.
