Math Bugs Me!


These cheerful, illustrated introductions to middle school math concepts come from Santa Ana (CA) teacher Sherry Skipper-Spurgeon's 6th and 7th grade classes.

Learn about

  • Basic Geometry Terms
  • Eek! Percents
  • Easy-peasy! Slope & y-intercept
  • It Matters: Order of Operations
  • Who Is Average anyway?

... and much more.

Thanks to Skipper-Spurgeon for letting us know about her MathBugsMe.com site through TODOS: Mathematics for ALL.

Alert: free online seminar with Tom O'Brien tomorrow

PoW taking place: math problem-solving moment of the week

"You don't even have to do the division. You just need to think."
- Rebecca A, highlighted in the Algebra PoW's Latest Solution

TeX the World


Avital Oliver's add-on to the Firefox browser takes TeX typesetting on any website and renders it as an image. TeX the World runs every 3 seconds on interactive websites, so it marks up chat sessions as well as HTML-enabled webmail, embedding symbols on the fly directly into correspondence.

Now taking place: math education conversation of the hour

"Here's a site with some fun graphics that my students thought were cool. In particular, take a look at the graphic of 'Facebook Breakups.'"
- Corey Null, posted to the AP-Statistics listserv

Thank You, Melissa
