This worksheet is about reading numbers written in words and writing them using numbers.

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....

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