the back in large print, the light shows through the card. Your student will soon learn all that has to be done is read the number backward, and they have the answer.
Hold at least two cards at a time, to keep the light from showing through.

Multiplication is built on a knowledge of addition.
Division is built on a knowledge of subtraction.
Without these foundations, math will always be confusing and frustrating.
