Pre-algebra

No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

Arithmetic properties

This tutorial will help us make sure we can go deep on arithmetic. We'll explore various ways to represent whole numbers, place value, order of operations, rounding and various other properties of arithmetic.

Factors and multiples

Understanding and finding factors and multiples. After these videos, you'll be ready for fractions.

Reading and interpreting data

This topic is less about statistics and more about interpreting data--whether it is presented as a table, pictograph, bar graph or line graph. Good for someone new to these ideas. For a student in high school or college looking to learn statistics, it might make sense to skip (although it might not hurt either).

Measurement

From length to area to volume to time, thinking about how we measure things.

Fractions

Understanding fractions conceptually, using operations with fractions, and converting fractions.

Decimals

Understanding decimals conceptually, using operations with decimals, rounding and estimating with decimals, and converting decimals.

Negative numbers and coordinate plane

Extending our understanding of numbers below 0. Thinking about "absolute" distance from 0. We will also look at all 4 quadrants on the coordinate plane.

Ratios, rates, proportions

Learn all about proportional relationships. How are they connected to ratios and rates? What do their graphs look like? What types of word problems can we solve with proportions?

Equations, expressions, and inequalities

In this topic, we will look at 1- and 2-step equations, as well as expressions and inequalities.

Exponents, radicals, and scientific notation

Understanding and solving exponents, radicals, and scientific notation without algebra.
