I asked them "What's going on with the dots?" At first they noticed the pattern of colors. Something that I didn't even notice. But soon after that they noticed things like prime numbers forming a circle, factors of 3 forming triangles, factors of 4 forming squares, factors of 5 forming pentagons, etc. Although we weren't talking about factors explicitly today, it helped them to continue to think about patterns and was a nice way to get their brains thinking about math.

Teach 180: Dance Factor Dance (Day 164)
We are continuing to look at patterns in PreCalculus. As students walked in the room today, I had the website www.datapointed.net/visualizations/math/factorization/animated-diagrams/ open. The short screencast here you through the first 30 seconds of what they saw. (Music is called "Sunglasses" courtesy of "Loyalty Freak Music".)
