I received a Google Wave invite from a follower on Twitter... but now what? My username is klb925@googlewave.com, so please add me if you have it! I'm thinking that it's like Twitter and it's all about who you follow and who follows you. Time will tell!

I started probability today in my general classes; instead of just going right into the new info, I had the kids all grab a white board and marker and eraser and told them to draw 5 dashes. I set up the random number generator on my virtual TI (on my tablet... I mean, on my colleague's tablet - I still don't have mine!). Their goal was to get the biggest number possible by placing the digits as I gave them. The kids seemed to enjoy it - they wanted to add additional spaces and then we switched to the smallest number possible. I gave the student in each class with the most wins some extra credit. After we finished, we talked about the probability of making the number 99999 - they were amazed to find out that you'd have a 1 in 100000 chance of getting 5 nines in a row! It was a great intro to what we'd be talking about. Many thanks to Dave Marain at MathNotations for the idea!
