As students master a level of multiplication facts, they should immediately begin a study of the inverse facts. Introducing the levels in this prescribed manner speeds up the way the brain receives and stores the facts preparing them to rapidly move forward and backward on the number line with fluidity.
It is commonly thought among educators that students with mastery of multiplication can divide by just flipping known multiplication facts. Research challenges that thought. Addition and multiplication are stored together in the brain since multiplication is rapid addition.
However, subtraction and division are stored together but separate from addition and multiplication. Therefore, students can only master subtraction and division when they are caught because they were taught…not by default of knowing addition and multiplication.
The Math Facts Matter Levels are designed to smoothly and quickly transition the student from addition and subtraction into multiplication and division. NOTE: Addition is an absolute prerequisite to multiplication. Students struggling with multiplication, regardless of their age, should first master addition.
