So what could I do to "ignite" thinking about mathematics education given the constraints of using 20 slides and just 5 minutes (with the slides auto-advancing every 15 seconds)? This was the challenge I faced as November 6 approached and I prepared for a so-called Ignite event. The result? See for yourself at Key Curriclum's Sine of the Times blog. Be sure to check out the other presenter's ideas, too, on You Tube. I am sure you'll find something to ignite your thinking about mathematics teaching and learning!
