## Group Exploration in Math

I am often asked how to get learners to spend more time “exploring” in their learning rather than just recalling or responding to specific prompts for information. Exploration of the learning space is particularly important because learners find the interesting nooks and crannies of the concepts that they would not otherwise discover. Let me share an example. Yesterday in class we needed to spend more time on exponential functions. I began class by displaying a graph of y=2^x and asking the class specific questions like “The graph of an exponential function has an asymptote, where is it?” Only to...

## 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!...

This is a short TED Talk by Rob Reid (The \$8 billion iPad) that tries to infuse a little “reasonability test” into our blind belief in the numbers provided by those with self-interest … in this case, the music/entertainment industry.   There are several examples that you could turn into signed number addition or subtraction problems.  In my favorite example (about 2:57 in the video), Reid uses what he calls “Copyright Math” to “prove” that by their own calculations, the job losses in the movie industry that came with the Internet must have resulted in a negative number of...

## Scale of the Universe

One of my former students (who is still a Twitter user) pointed me to this fantastic animation of powers of 10 meters, called “Scale of the Universe 2.”  I think you’ll appreciate the design and relevance of the objects the authors, Cary and Michael Huang, use to help the user to understand the relevance of scale.  Just like Powers of 10, you can zoom from the smallest part of a cell to the edges of the universe.     The authors have a collection of science- and math-oriented animations at HTwins.net that might be worth checking out too.  They also have...
