Free Online Math, Science, Finance

Khan Academy is a non-profit website site where you can access free online math, science and finance lectures. When you visit you'll see subjects under group headings like Algebra, Trigonometry, Calculus, Physics, Chemistry, SAT Preparation, and Arithmetic.

Under each subject, such as Arithmetic, are listed all the topics, such as Dividing Decimal Numbers. Click on the link and you'll be taken to a YouTube video, such as this one here.

Khan Academy looks like a really amazing resource. Not only are there all the video lectures, but there is also a curriculum, with exercises to work, for some of the math topics, including Arithmetic and Algebra 1. Here is the link to the Khan adaptive math program. I didn't go in and look to see how the exercises are presented because you have to register for that part, but I recommend you check it out if you're looking for a new way to do math.

Now I'm wondering if I could have avoided some of the $$$ I've spent on math curricula over the last 6 years of homeschooling...

Free Math Learning Links and Stuff

There are many wonderful websites with free math activities for you to use with your kids. Some of the links are also great if you need, or want, to brush up on, or advance, yourself in math, or maths (as it is called in the UK). All of the links below were sitting in my bookmarks folder - the result of many years of gathering resources for homeschooling. Masses of free math stuff, in no particular order:

• HomeschoolMath.net has a host of free worksheets, interactive tutorials and quizzes, curriculum guides, help on teaching, and links for online games. The site owner Maria also runs the Homeschool Math blog.
• Try Cool Math 4 Kids for a host of very colorful, free, interactive math games. Their companion Cool Math site has activities for the age 13 and up crowd.
  
• At Multiplication.com you can: download flashcards, worksheets and quizzes; find oodles of free resources for teaching the times tables; and find fun, free, colorful math games for kids.
• On the much less colorful front, download a variety of free online graph and grid papers. The variety of papers here is quite surprising - includes celtic knot paper, perspective paper, triangle paper, axonometric paper and tumbling block paper. I'm not sure what you do with all these, but I'm sure your kids will have some creative ideas!
• Personally I enjoy the patterns in mathematics. Boys are often fascinated by codes and ciphers and the accompanying spy stories. Here are some teaching resources for codes and ciphers, or visit Bletchley Park, the home of secret British codebreaking activities during World War II.
• Moving into more advance mathematical concepts, you can find a free online geometry textbook at Learner.org. Mathematics and art are very related. Learn about Fibonacci numbers and the golden section in art, music and architecture, or study geometry in art and architecture.
• Hippocampus has free Algebra courses.
• This Statistics site is not for the faint of heart - see the best and worst of statistical graphics. It's free and you just might learn something. What more could you want?
• Or maybe you'd prefer a little, light, free Calculus. Something new, or indepth and old is good for the brain cells :-)
  
• Last, but not least, Math Forum - dedicated to the teaching of mathematics.

I hope you find something of interest among these free math resources. Of course I do know of a few more links, which I will have to save for later.
