Algebra I is usually the first real year of mathematics after general math or arithmetic, and is usually taken in grades 8 or 9. Algebra, by definition is "the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formula and equations." Obviously, it is one of the most foundational parts of mathematics, and many jobs utilize is it, such as electricians, plumbers, carpenters, engineers, programmers, financial planners, and more. Whether you plan to have a job using it or not, everyone should learn Algebra due to general benefits like challenging your brain and using problem-solving skills. Core concepts of Algebra I include solving and graphing linear equations and inequalities, graphing and evaluating functions, simplifying and factoring polynomials, using the quadratic formula, and more. Below are links to other pages of the website, teaching those core ideas and more.
In Unit 1, basic topics that give you the intro to Algebra 1 are introduced. Additionally, this unit should not be glossed over, due to its importance and "foundation" for the rest of algebra. The 6 sections covered in the unit are:
the real number system and properties of real numbers, order of operations (PEMDAS), algebraic expressions and solving one-step equations, evaluating expressions, solving two-step equations, and solving inequalities.
In Unit 2, you learn about more advanced equations, with the main focus of manipulating different expressions to get to your answer. The 6 sections covered in this unit are:
combining like terms, distributive property (expanded), simplifying expressions, solving multi-step equations, variables on both sides, and infinite/no solution cases.
