The Associative Property of Addition and Multiplication
The Associative Property of Addition and Multiplication is another fairly simple and straight forward property for developing number sense and understanding. The property simply states that in addition expressions and multiplication expressions, numbers can be grouped (or associate) differently without changing the value of the expression. What this means is: In the first expression (2…

The Commutative Property of Addition and Multiplication
The Commutative Property of Addition and Multiplication is a fairly simple and straight forward property for developing number sense and understanding. The property simply states that in addition expressions and multiplication expressions, numbers can travel (or commute) to either side of the operation symbol (the ‘+’ or the ‘x’). What this means is: Notice how…

The Additive Property of Numbers
One of the most basic properties to understand is that numbers are made by adding (or subtracting) separate numbers to (or from) one another. This is to say that a number can be constructed from two or more separate numbers AND numbers can be deconstructed from a singular number into two or more separate numbers.…

The Importance of the Math Components
Math has three important components with which any learner can have different levels of aptitude; computational fluency, number sense, and problem solving. On their own, each of these components have their rightful place in the learner’s toolbox. Combined, however, the three components unlock (or lock up) the comfort level of a user. The first is…

Facts, Facts, and More Facts
Teacher: Practice your math facts.Student: Why do I have to memorize these?Teacher: Because I said so… These words were all too true when I was in school many (MANY) years ago. I was the type to do as I was told, so I studied my math facts. Unfortunately, not everyone does. For whatever reason, absorbing…
