This tool is more than the "numbers on a line" that you can buy at your local teacher store. This number line gives you stickers so that you can color code all the multiples to aid children in skip counting, recognizing number patterns, teaching odds and evens, and learning their multiplication and division facts. It provides the true visual aid that children need in learning number relationships. You can even purchase the negative numbers section for upper grades.
Here are pictures the number line in my classroom.
For example, note that all the even numbers have red stickers and are multiples of two.
I can't tell you how many "A-Ha!" moments I've heard from my students using this number line! If you are interested in purchasing it, click here Kim's Number Line.
