This is a great site “for kids 13-100” with games, explanations of functions and other high school level topics. It has a graphing calculator – you enter an expression like x^2 +2, hit the “Eval” button and the graph draws itself. I’ve seen many online graphing calculators, but this is the first I was able to intuit how to use on the first try.

This is a terrific website maintained by a man named Clay Ford just for fun. The site is entitled “Curious and Useful Math” and contains several games, tricks, weird patterns that happen with numbers (like what happens when you square 111,111,111). The writing style is clear and the tricks work.

This is a site by a Canadian company ACT360 Media Ltd. in connection with Microsoft. You need to register (for free) to use the math section, but the problems are great for high school level math, so I think it’s worth it.

This is a neat demonstration of what large numbers of pennies look like. It would be nice to visit this when you are reviewing ideas like place value and orders of magnitude.

This is a review site for high school and college students, which has algebra and trigonometry sections as well as traditional college topics like calculus. The level of language is rigorous, so most students would probably want to use other, simpler sites first but then go to this one to get adjusted to formal math writing.

This is an award winning commercial site with a frequently changing list of top sites in math education. There are also online tutorials for tutors, but I’ve never explored them and don’t know if they are available only to members.

http://educationplanet.com/topsites/math.html

I like the way this site divides its list into the top twenty sites by topic. You can also access Kathy Schrock’s Guide from this page. (The Schrock Guide is a now part of the Discovery Channel and has a wicked URL.)

This is a site by Jim Martindale hosted by University of California at Irvine. I list it here because the math calculator section lists oodles of site for online math calculators, but the site itself is an amazing college reference desk with fascinating features like a world map you can click on to zoom in on images of your country.

The Massachusetts Department of Education site is the place to go for copies of last year’s MCAS exam (with answers).
