Prealgebra Help

Prealgebra is a class typically taken by students in grades 6-8 that offers preparation for algebra 1 topics. Prealgebra is slightly more advanced than basic arithmetic, but it is not as advanced as algebra. In this section, students will find a basic introduction to classifying numbers, unit rates, ratios and proportions, data representations, and more!

And, if you're still stuck after reading through these pages, contact a prealgebra tutor today!


Algebraic and Geometric Patterns

Learn the definitions of groups and patterns, and learn how to solve find the keys for algebraic and geometric patterns!

Choosing the Best Representation of Data

Which type of "average" is the best? This takes the concept of mean, median, and mode learned in elementary math and shows how to apply it in useful ways.

Estimation

Estimation occurs when you use the data you have to make an educated guess. In this section, you'll find some helpful steps to make a good mathematical estimate.

Integers

What is an integer? You'll find the definition, as well as a quick practice quiz, here.

Introduction to Exponents

You've probably seen that "tiny number" next to "regular sized numbers" tons of times. It's called an exponent! Here, you'll learn how exponents change values of numbers, and how they fit into the order of operations.

Introduction to Square Roots

A square root, or radical, symbol might look like a division sign at first, but beware! Square roots ask you to find roots, or factors, of a number in a very specific way. Here, you'll learn the basics of square roots as well as the rules on positive and negative roots.

Isolate X - Effects of Cross Multiplication

Learn how to evaluate problems like C = A/B using cross multiplication. Use this quick guide so you won't be confused again!

Ratios and Proportions

Ratios and proportions are often written the same way; therefore, they are often confused. Here, you'll learn the difference between a ratio and a proportion. You'll also get to test your knowledge to make sure you can adequately use both ratios and proportions in practical situations!

Scatterplots

Scatterplots are one of the easier graphs to make and to interpret! Like many graphs, scatterplots show relationships between two different variables. Here, you'll find an example of a scatterplot as well as instructions as to interpreting its meaning.

Simple Probability

This lesson will guide you predicting simple outcomes from events, like flipping a coin or rolling a die. Knowing the basics of probability will certainly help you figure out how likely events are to occur!

Unit Rates

Any time you work with measurements, you need to make sure that the unit labels on the measurements are properly written and (if necessary) converted. This lesson shows you how to make sure the units stay consistent in all of your calculations.
