Algebra I

Algebra is everywhere, and in this "a-g" approved course you'll learn how to solve everyday math problems using it.


Algebra is everywhere. It’s used for everything from calculating a college’s rank to determining a car loan’s monthly payment. Through this course, you’ll learn how to use algebra to solve everyday life problems, from calculating how much gasoline you’ll need for your summer road trip to graphing college tuition costs. With an in-depth understanding of algebraic principles, including variables, equations, graphing, number properties, polynomials, and more, you’ll gain the necessary problem solving skills to practically apply algebra to real life. This course is “a-g” approved and can be used to supplement a face-to-face Algebra I class. PREREQUISITE: Mathematics competency through 7th grade.
