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.

Word variety - one of seven videos in a series on kindergarten prep created by the Anoka-Hennepin School District. Using a variety of words in talking with others is one of the skills that provides a strong foundation for learning and success in kindergarten.

Does your child use complete sentences with four to six words. Communicate needs and feelings appropriately? Try to use new words?

A shocking discovery out of a Baltimore City high school, where Project Baltimore has found hundreds of students are failing. It’s a school where a student who passed three classes in four years, ranks near the top half of his class with a 0.13 grade point average.

Tiffany France thought her son would receive his diploma this coming June. But after four years of high school, France just learned, her 17-year-old must start over. He’s been moved back to ninth grade.

“He's stressed and I am too. I told him I'm probably going to start crying. I don't know what to do for him,” France told Project Baltimore. “Why would he do three more years in school? He didn't fail, the school failed him. The school failed at their job. They failed. They failed, that's the problem here. They failed. They failed. He didn't deserve that.”

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

The distinctive feature of the Italian Army in World War Two was its poor and insufficient armament.
Even though weapons produced at the famous Italian arms factory Beretta were of the highest quality, the rest were known for their very low quality or obsolete nature.
