Algebra I—Semester B
Double the equations, double the fun.
Whether it's your saving grace or your worst enemy, there's no getting around it. Algebra is a part of life. The sooner we accept that, the better.
The fact is no matter where you go or what you do, you'll want a functional relationship with algebra. Its graphing skills are off the charts, and it can simplify your life like no other math can. Sure, it might be a bit radical and irrational from time to time, but it isn't half bad if you just give it a chance. Who knows? It might even be the start of an unlikely friendship. (You + Algebra = BFFs.)
Semester B is chock-full of stuff that we haven't come across in other math classes. We'll start out in familiar territory with systems of equations, but we'll quickly move on to radicals and quadratics, lines' curvy cousins. That'll open the gate to polynomials and rational expressions, which are all about factoring. (And plaid! They're pretty stylish.) Once that's done, there's a 99% chance we'll finish up with probability and statistics.
P.S. Algebra I is a two-semester course. You're looking at Semester B, but you can check out Semester A here.

- A scanner (or access to one)
- A camera (a camera phone is sufficient)

Course BreakdownPurchase units individually
Unit 7. Systems of Equations
After having graphed linear equations and learned the bare bones of functions, we'll solve and graph systems of linear equations. Whether they're given as equations or word problems, we'll be able to tackle these problems in their many forms. Wear a helmet, though. The last thing you want is a concussion.
Unit 8. Radicals and Quadratic Equations
We'll start by performing major arithmetic operations on square roots and by the time this unit's over, we'll be able to wrangle radicals just about anywhere. That'll lead us into quadratic equations, which are like linear equations with more twists and turns. (We're not kidding. Have you seen them behind the wheel?)
Unit 9. Polynomials
Polynomials are all about factoring. They also have a fondness for Bocce ball, but that's not as relevant. Once we learn a thing or five about factoring, we'll be able to understand polynomials on the equation level. And if you really want to connect with polynomials, consider joining in a round of Bocce ball.
Unit 10. Division of Polynomials
Right when you thought you knew all there was to know about polynomials, we go and start dividing them. Luckily, all our old factoring tricks will still apply and they'll be even more useful as we start dealing with rational expressions. Too bad they aren't nearly as rational as their name suggests!
Unit 11. Probability and Statistics
We’ll start out with the beautification of data, because data alone is just boring. Get ready for stem and leaf plots, bar graphs, histograms, pie charts, box and whisker plots, and finally scatter plots. Then, we'll move on to probability, which is probably going to be fun. Actually, scratch that. It's definitely going to be fun.
