How ColorMyMath teaches it

The number line keeps going: below zero, between the whole numbers, and far past 100. Every position is a place you can land on and see.

Every page is free and open — nothing to install, no account, and it works on a phone or a classroom board. Every number has its own color: 1 red, 2 orange, 3 yellow, 4 green, 5 blue, 6 purple, 7 brown, 8 pink, 9 cyan, and a number is that many colored dots.
