How ColorMyMath teaches it

Ratios are built as tables and pictures of the same recipe scaled up and down — the relationship is drawn, not just written.

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.
