Pre-Algebra—Semester B

The shape of Shmoop's heart.

Pre-Algebra can be a little, well...scary. Working with equations, graphs, and not one, not two—but an infinite amount of numbers? Sounds pretty terrifying if you ask us. Maybe not as terrifying as a tarantula the size of your face, but not too far off.

Good thing we've got all the tools you need to conquer even the worst obstacles Pre-Algebra can throw your way. From rational numbers and equations to statistics and probability, we'll be cheering you and leading you on. Plus, you'll need someone there just in case you get tangled in a giant spiderweb or something.

In this course, we'll throw readings, activities, and problem sets your way as you cover concepts that we'll see again and again.

  • Can't get enough equations? We’ve got oodles of systems of equations with your name on 'em.
  • We'll learn the basics of geometry develop a strong connection with congruence, similarity, and volume.
  • Tackling statistics and probability has never been easier. Well, probably.

Equations and other concepts tend to rear their beautiful heads in all math classes at some point. Luckily, Shmoop makes these concepts easier to learn and remember.

P.S. Pre-Algebra is a two-semester course. You're looking at Semester B, but you can check out Semester A here.

    Unit 9. Systems of Linear Equations and Inequalities

    On occasion, lonely linear equations and inequalities are known mix and mingle together. Equations that don't know each other very well will try to find similarities between them. Hopefully they'll be able to find a point in common and connect in some way before the evening ends.

    Unit 10. Basics of Geometry

    Geometry is all about seeing the world around you in a totally different way. (No, not upside down. Now get off of there.) We'll describe shapes, calculate side lengths, find congruent angles, and manipulate formulas for our own personal gain. And let's be real: who doesn't love using just about anything for their own personal gain?

    Unit 11. Transformations in Geometry

    Prepare for more reflections than a fun house full of mirrors, more rotations than a pirouetting ballerina, and more translations than a U.N. conference. As long as we get our shrink ray working, don't blow things out of proportion, and hold on to our congruent angles, we'll be just fine.

    Unit 12. 3D Geometry

    The third dimension involves a lot more algebra than you might think. Dust off those area formulas, one-variable equations, and proportions, because we'll be putting them to good use. Get ready to fold some nets, calculate volumes and surface areas, and identify similar solids. Thrilling, we know.

    Unit 13. Statistics

    Statistics allow us to sample populations, gather data, calculate means, and create colorful graphs that report our findings. It's all about making a lot of information more easily understandable. That, and proving once and for all that Michael Keaton is the best Batman of all time.

    Unit 14. Probability

    This unit will focus primarily on being able to predict the future. (Think less divination and more blackjack.) We'll draw tables and diagrams to represent probabilities of different events, calculate the chance of winning a poker hand and the lottery, and dabble in the art of simulations, all to bring probability to life. Probably.
