Properties of Real Numbers: Mixed Review

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Zero in on a commonly mistaken property. The video instructor shows several examples of expressions raised to the power of zero. Each example incorporates a different exponent property and highlights common misconceptions.

Apply solving linear equations to averages. A helpful video presents an average age problem given two unknown ages. Pupils learn how to set up the problem from the given information. They see how the equation is reduced to a two-step...

Classify numbers into their groups with this graphic organizer for the real number system. The printable provides a space for all the categories, with a separate column for unreal numbers.

A real number is any number that you can find on a number line. This includes rational and irrational numbers, which means positive numbers, negative numbers, decimal numbers, square root numbers and even pi.

Clarify for young scholars the basic properties of addition and multiplication with this foldable math resource. Written on the front flaps are the terms commutative, associative, identity, and inverse...

Learners analyze the real number system. They discuss real numbers, rational and irrational numbers, integers, whole numbers, natural numbers and more of the real number in the system. They differentiate between all these numbers.

Natural numbers, whole numbers, integers and rational numbers begin this lesson on the real number system. You can also learn more about the number line and absolute value. Examples and diagrams are included to enhance understanding.

Learners use paper cups and colored chips to observe properties of operations with real numbers. As a class, students brainstorm and use manipulatives to demonstrate associative, commutative, distributive identity and inverse properties....

Learners sometimes struggle to understand the concept of adding and subtracting integers. Help them see the why behind their answers using the interactive number line. The values change as individuals adjust the number line for each new...
