Math Flash Cards

Mental Subtraction (1-12)


This module continues to work on mental calculation. The previous card deck, Concept of + – (1-12) taught the concept and used physical movement of the cards and numbers.

This module continues to work on how to move the numbers in your mind without physical movement or counting with your fingers. In a sense it is making the brain work harder.

After this module the child will be able to “borrow” in their mind mentally. It will make the brain stronger and faster and continue to increase the confidence of the student.
