Celebrate the Errors in Math Practice

Dear math students, As you work through your mathematics practice, I’m going to challenge you to embrace making errors in an entirely new way.  Many students believe that every problem in math homework should be perfectly constructed with no errors. It might look something like this:   But when it’s time to study after the initial problem run-through, what does this perfectly constructed problem say? Does it coach you on remembering how you struggled? Does it remind you where you made an error? No. When you make an error as you’re working a problem, please don’t erase it from the face of the...

WolframAlpha Facebook Report

This is a delightful exercise that everyone seems to love. WolframAlpha will provide you with an extremely detailed analysis of your own Facebook data including visualizations, world clouds, graphs, and more.       Here’s how: Go to WolframAlpha.com.

Wait while the data is analyzed. Note: Sometimes the report seems to stall after 100% of the data is analyzed. If this happens, simply repeat steps 1-3. The second time, the report seems...

Level Up: Video Games for Learning Algebra

Last week I gave a presentation at AMATYC about video games for learning algebra. As usual, Mat Moore did a fantastic illustration for the prezi. It was staged in five levels: Level 1: Why use games? Level 2: What is a game? (manipulatives, puzzles, and games) Level 3: Become a Math Game Critic Level 4: Play GOOD Games Level 5: Good Algebra Video Games? You can click through the Prezi below.

Coming out of the Closet: I’m a Game Designer!

I don’t even really know how to begin here. For the last three years I’ve been working on a secret little project that I wasn’t allowed to talk about in public (NDA). I’ve been designing digital games for learning algebra in my (ha ha) free time. The last couple months have been an absolutely insane flurry of activity as we approached the launch date and as a result, I haven’t posted much. Finally I can tell you that I’m no longer a wannabe game designer. I’ve designed four game apps that are now out in the iPad App store!...
