Mathematical Properties

A student-made poster uses symbols to represent mathematical properties.

Commutative, Associative, Distributive, Inverse, and Identity. Not your everyday words unless you are an 8th grade MRMS student. These properties of mathematics are the foundation of all future mathematics understanding. Under the new Common Core Curriculum, a key mathematical practice is to create viable arguments and critique the reasoning of others. Why is 4+0=4?...the additive identity of course! The properties are already being used to justify solutions when solving equations, multiplying monomials, and more.

In 8th grade, students transition from numeric representations to algebraic representations. Check out these awesome projects from various 8th grade math courses. After several days of instruction on properties, students were asked to use symbolic representations of the mathematical properties (i.e., a smiley face plus zero is equal to a smiley face). The students really solidified their understanding of the properties. We were proud of their creativity and it was a great opportunity to share their knowledge.
