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.

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?

Get more kindergarten info at: www.anoka.k12.mn.us/kindergarten or at: www.anoka.k12.mn.us/enrollment.

Improve your students' reading and writing skills by introducing them to a variety of synonyms with the synonyms list chart. This poster features an alphabetical list of commonly used words and their synonyms.

Use this chart with students in grades three through six to improve their vocabulary. An improved vocabulary will help increase reading fluency, word recognition, and diction. This poster comes with reproducible sheets, activities, and teaching tips on the back. The 17" x 22" size ensures that students will be able to see the poster from their desks or tables.

The chart from Trend Enterprises can also be used as a great starting point to discuss connotation and denotation with your upper elementary students. You can use it with student writing by asking them to use synonyms for often repeated words in their writing. When students become familiar with the chart, it can be used as background knowledge to teach students about using a thesaurus.

Specifications for the synonyms words poster:

Dimensions: 17" x 22"
Synonyms listed in alphabetical order
Reproducible sheets, activities, and teacher tips on back
Suggested grade range: 3rd to 6th
Suggested ages: 8 to 11

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!

Inflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa. They can be found by considering where the second derivative changes signs. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or undefined. Created by Sal Khan.
