High school math videos - free

Today I wanted to highlight two companies that both offer lots of free high school level math materials in the form of videos. These are real, commercial companies, yet they have chosen to offer the videos online for free. Both have something else they sell, hoping to make some money obviously from that part of the business.

The video content can really be of help for all students, teachers, or parents who need additional help with high school math (algebra, geometry, calculus). And since I'm highlighting these two, if you have a topic you have trouble with (such as polynomials or factoring or inequalities) you can even check out videos for that topic in both places.

1) BrightStorm Math.

They currently have over 2,000 videos available for free - a free registration is required though. Algebra through calculus. What they are selling is test preparation courses.

2) MathTV.com


MathTV.com has over 6,000 free math videos, including some in Spanish. Prealgebra through calculus. What they are selling is their own textbooks, physical and online. However, their online textbooks are available for free for evaluation and class testing through June 2010.

These are great links... I am co-founder of a company called TutaPoint, based in New York. We are working hard to produce math videos for high school students that are aligned to the NCTM concept areas.
Also, we have technology to add an interactive quiz at the end of each video.
While we don't offer them free, we have many partnerships to provide the videos to schools / home schooling students.
Would love your thoughts on our list: http://www.tutapoint.com/resources/math/videosresult?view=all

Brightstorm is really great!
I work for Thinkwell and while we produce online curriculum that we charge for, we offer a slew of our videos for free on YouTube. http://www.youtube.com/user/ThinkwellVids

We figure you can check out the videos to get a taste of our courses. If you like them you can purchase them.

Thanks for posting these links! I am a self-taught homeschooler, and these sites will be very helpful when I start calculus next semester.

Meaning of factors in multiplication: four groups of 2, or 4 taken two times?

Someone asked me about the interpretation or meaning of the two numbers in multiplication, such as 4 × 2. Do you view it as four groups of 2 , or as four, taken two times ? Here's their question: "...I noticed that your explanation about how to interpret a math phrase, such as 4 × 2, is different from how I have understood it and taught it to my older daughter who was using RightStart Math at this level. Let me explain:  I see that you are using the first factor to denote number of groups and the second factor tells how many are in each group (4 × 2 would be interpreted 4 groups of 2).  On the other hand, I have taught and thought of it reversed, with the first factor telling how many are in each group and the second factor telling you how many groups (4 × 2 would be 4 taken 2 times).  I know that the difference in explanations does not ultimately change the product, but I am wondering what you thoughts are.  When I conceptually picture what I'm doing I see it as 4

Geometric art project: seven-circle flower design

Image
I got inspired by the blogpost Art School | Geometric Design with Islamic Art where Deborah shows how to make a neat flower design with seven circles , using a compass, and then coloring it using 2, 3, or 4 colors (or however many of your own). I think it ties in neatly with mathematics, and lets students practice drawing circles with a compass.  My girls loved the art/math project. Here are pictures they made: Here are step-by-step instructions for the flower design: 1.  Draw a line and a circle so that the circle's center point is on the line. Then mark the points where this circle intersects the line. 2. Use those points as center points, and draw two more circles. The radius is the same all the time, so make sure you don't change it on your compass!We used 5 cm as the radius, and that made the whole design fit neatly on a regular letter size paper. 3. Now note the two points marked in the picture. They will be used as center points in the next
