How ColorMyMath teaches it

Lengths, areas and volumes are built from the same dots, one more direction each time. Measuring means laying real units end to end with no gaps.

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.
