7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations.
7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics.
(Content was selected for this grade level based on a typical curriculum in the United States.)
You know how to add and subtract whole numbers like 7 and 42, but fractions are numbers too. And just like whole numbers, you can add and subtract them. This tutorial will show you how!

What is 2/3 of 2/3? If 4/7 of the class are boys, how many boys are there? Multiplying fractions is not only super-useful, but super-fun as well.
Did you also know that fractions can represent division (and the other way around). We can create fractions by dividing whole numbers and then even divide the fractions themselves. We'll see that dividing by something is the exact same thing as multiplying by that thing's reciprocal!

If you already know a bit about both decimals and fractions, this tutorial will help build a bridge between the two. Through a bunch of examples and practice, you'll be able operate in both worlds. Have fun!

You've already got 2 cups of sugar in the cupboard. Your grandmother's recipe for disgustingly-sweet-fudge-cake calls for 3 and 1/3 cups of sugar. How much sugar do you need to borrow from you robot neighbor?
Adding and subtracting fractions is key. It might be a good idea to look at the equivalent fractions tutorial before tackling this one.

You know that fractions, decimals and percentages are all ways to represent rational numbers. In this tutorial, you'll take things to the next level by using these representations together to solve problems.

At least 50% of the math that you end up doing in your real life will involve percentages. We're not really sure about that figure, but it sounds authoritative. Anyway, unless you've watched this tutorial, you're really in no position to argue otherwise.
