Number Properties - Know 'em, Like 'em, Use 'em

Who says math is boring? Turn dry concepts like properties and vocabulary into an interesting lesson! Examine the commutative and associative properties of addition and multiplication using geometric reinforcement. Through collaboration,...

I can multiply, so why can't I add these radicals? Mathematicians use the distributive property to explain addition of radical expressions. As they learn how to add radicals, they then apply that concept to find the perimeter of polygons. 

Won't the other properties be sad to learn that they're not the most important? The 11th installment of a 35-part module is essentially a continuation of the previous lesson, using logarithm tables to develop properties. Scholars...

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

A series of problems involving exponent properties is the focus of this video. Sal demonstrates rational expressions, simplifying fractions, and how to manipulate algebraic equations using exponents and division.

Recognize the base. Part of a larger Algebra I series, the short video highlights the importance of recognizing the base to simplify expressions with exponents. In doing so, pupils notice the basic property that uses negative exponents.

The symbolic nature of mathematics is perplexing to some scholars. Help them out using a video lesson that offers explanations and examples of how to read a mathematical sentence. By translating expressions and equations into words,...

Two expressions equal to a third are also equal. The resource provides a short explanation of the transitive property. The video gives examples of the property in action.

If you know how to use the distributive property and you know how to combine like terms, then you can simplify this expression.
