Rainbow Math is a routine designed to help students practice their math facts and gain automaticity with facts. Grouped in sets of 10 flash cards at a time, students add on additional facts as each level is mastered (each level is a new color).

Students are motivated to practice and learn their facts so they can add all the colors of the rainbow to their ring.

The process continues with subsequent steps to map out the solution.
