Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.
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.

NOTE: Around the 4:40 mark, we mention that President Ford expanded the celebration of Black history from one week to the full month 50 years after President Lincoln announced the Emancipation Proclamation. The correct number is 113 years later. We apologize for the error.
Every February, Americans use the month to reflect on and celebrate the achievements of African Americans in American history. That is what Black History Month is all about. In this video for kids, you will learn how this particular month-long celebration came to be. At one point, the country didn't even study any events related to African American history because it dealt with such a tragic period in our history. In 1915, an African American historian named Carter G. Woodson decided to change that. "You must give your own story to the world," he wrote.
Woodson recognized that the predominately white historical association from which he was banned had no interest in attributing advances in science, technology, and other fields to non-White people. And very few people studied Black history at this time. School textbooks didn't even contain information about it. To give proper recognition to the accomplishments of Black Americans, he started the Association for the Study of Negro Life and History and declared the second week in February as "Negro History Week."
Carter Woodson chose this week because it commemorated the birthdays of two significant historical figures related to the freedom and equality of African Americans: Frederick Douglass and Abraham Lincoln. Frederick Douglass was an abolitionist who was born enslaved in the early 1800s. He was able to escape to the North and declared himself a free man, becoming an abolitionist and advocate for human rights. He met Abraham Lincoln on several occasions and may have influenced Lincoln's ideas on slavery.
It wasn't until Gerald Ford was president of the U.S. that the week-long celebration of Black history became a month-long period instead. Black History Month matters because it celebrates the sacrifices that so many Black Americans faced and endured to bring the country to where it is. As former President Obama stated, "We recommit to reaching for a day when no person is judged by anything but the content of their character."
We hope you and your student(s) enjoyed learning about Black History Month! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!
