In 3rd grade math we want you to start using bigger numbers and start multiplying and dividing, too. By the way, did you know that some numbers aren’t actually “whole?” They’re “partially whole.” We call them fractions! We want you to start playing around and having fun with those, too. There’s also area, perimeter, and place value to be discovered. Whew. We have so much to do and can’t wait to do it with you. Let’s go! Want a virtual coach for 3rd grade?

Coordinate Plane: Quadrants | Negative Numbers | 6th Grade | Khan Academy

You like dividing up a pizza into slices? In geometry, we slice up the coordinate plane into quadrants. Although these are more like squares than triangular pizza slices! Let’s learn about them. Practice this lesson yourself on KhanAcademy.org right now: Watch the next lesson: Missed the previous lesson? Grade 6th on Khan Academy: By the 6th grade, you’re becoming a sophisticated mathemagician. You’ll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data!

Coordinate Plane: Graphing Points Word Problem | Geometry | 5th Grade | Khan Academy

Naomi needs some help counting the number of blocks she walks from home to school. We’ll use the coordinate plane to graph it out first. Let’s go. Practice this lesson yourself on KhanAcademy.org right now: Watch the next lesson: Missed the previous lesson? Grade 5th on Khan Academy: Whether you are a robot, possum, magic unicorn, or just a normal human being, 5th grade is incredible! You will deepen your knowledge of the decimals that you were first exposed to in 4th grade. In particular, you’ll learn to do all the arithmetic operations–addition, subtraction, multiplication, division–with them and really understand what a decimal represents. This will be complemented by building your fraction muscles where you’ll learn to add, subtract, and multiply any fractions (and begin to divide them). On the measurement front, you’ll explore volume (or how much “space” something takes up) and continue the unit conversion journey begun in 4th grade. 5th grade is also the first time that you get exposed to the fundamental concept of graphing points on a coordinate plane, and you’ll get a very brief exposure to the concept of exponents (when exploring “powers” of 10)!

Exponents With Negative Bases | 7th Grade | Khan Academy

“Apply what we know about negative numbers to determine how negative bases with exponents are affected and what patterns develop. Also learn how order of operations affect the pattern. Watch the next lesson: Missed the previous lesson? Grade 7th on Khan Academy: 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.
