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. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Understand the connections between proportional relationships, lines, and linear equations.

Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

How do I find the equation of line given two points?
How do I find the equation of a line in y=mx+b form?
How can I practice common core math?

This chemistry video tutorial explains the concept of heisenberg's uncertainty principle in a simplified way. His principle applies mostly for small particles and events. As the uncertainty in the position of a particle increases, the uncertainty in momentum decreases. This video contains some math practice problems that illustrate Heisenberg's uncertainty principle.

Stanley’s African adventures can really only be appreciated if one looked at maps he had to rely on to survive. If you looked up Andriveau-Goujon’s ‘Carte générale de l’Afrique’ (1856) as an example, you will see a different Africa one with vast empty spaces. To be sure, it was a marked improvement to sixteenth century maps who used cyclops and giant elephants to hide their lack of knowledge, but yet you can still find fictional gigantic lakes and mountain ranges such as Lake Tanganyika and the Mountains of the Moon. Then, imagine you are tasked to find a single person in one of these entirely blank regions, while you also need to convince over a hundred strangers with you that this endeavor will be an undoubtedly dazzling success. Learn how Stanley even reached such an opportunity, having been born in Wales and disowned by his parents, to soon globetrotting and travel writing with his pockets continuously filled by the wealthiest of patrons.
