Teen numbers are numbers between 10 and 19. They're special because they're made up of a group of ten and some extra ones. Think of it like this: 10 is a full bus of friends, and the extra ones are friends who came in a separate car! So, 11 is a full bus (10) and 1 extra friend (1), and so on until 19! Let's practice recognizing and understanding these numbers.
Match the term with its definition:
| Term | Definition |

| 1. Ten | A. The number after 12 |
| 2. Eleven | B. The number after 10 |
| 3. Twelve | C. A group of 10 ones |

| 5. Fourteen | E. The number after 13 |
