This worksheet is about reading 2-digit numbers correctly.

The left digit tells you how many tens, like twenty, thirty, forty, fifty....etc.

The right digit tells you how many ones.

When the tens digit is 1, we have numbers like thirteen, fourteen, fifteen...etc....

When the tens digit is bigger than 1, we use twenty-, thirty-, forty-, etc....

We put a hyphen or dash between two number words, unless the tens digit is 1.

**Examples**

17 seventeen

38 thirty-eight

49 forty-nine

80 eighty
