Here's a classroom number line for ya! My kiddos love this number line for addition and subtraction, and the color pattern makes it easy for them to use. Not only is there an A-B pattern in the color scheme, but also an A-B pattern with even and odd numbers, so that your kiddos can easily identify even numbers, or skip count by 2s. You can also indicate multiples of 5 and 10 in any way you may choose. I place circles above the 5s and triangles above the 10s. However you choose to use it, I hope the colors pop in your classroom like they do in mine!
