Proof that rational times irrational is irrational | Algebra I | Khan Academy


By Khan Academy

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.

The Life Autistic Documentary


By Lumos Learning

Iowans with autism illustrate the nuances of The Life Autistic in this two-hour broadcast special. We meet twelve people of different ages and backgrounds, along with their families and caregivers, to understand the daily lives and future prospects of people with autism. Their stories explore diagnosis, early intervention, family life, treatment, education, employment and independent living. Interviews with experts, educators and advocates -- including famed author and speaker Temple Grandin -- provide greater context and a better understanding of the many expressions of autism. Tyler Leech lends his unique perspective as a member of Iowa’s community of people with autism to the stories from the original Iowa PBS web series.
