Unit 1: Classification and Operations of Numbers

In this lesson, properties of the set of real numbers and its subsets (natural numbers, whole numbers, integers, rational numbers and irrational numbers) will be investigated.

In this lesson, connections between and operations with decimal and common fractions will be examined.

In this lesson, knowledge of operations with positive decimal and common fractions, and whole numbers will be extended to operations with the complete set of rational numbers.

Unit 2: Exponents

Unit 3: Manipulating Algebraic Expressions

Unit 4: Radicals and Rational Functions

Unit 5: Prime Factorization
