## Ready when they can

- Read the word 'twelve' and identify it as 12
- Write the word form of a given number 1–20
- Match numeral cards to number word cards

## Lesson: Number words

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

*(drawing: Twelve stars. The word twelve means the number 12.)*

**Example.** 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.

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

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