Inside Track: Rainbow Addition Facts

Teaching Video:

The “Rainbow Facts” are pairs of numbers whose sum is 10. These are really useful facts for lots of everyday contexts, including shopping, where you are often subtracting amounts from 10 or 100.

Students can learn these using ten frames to show counters in two colours which add up to 10.
