The Probability of Rolling Up the Rim!

Believe it or not this is part of a formula to calculate the probability of winning in "roll up the rim". For those of you who are non-Canadians this is a promotional campaign for Tim Horton's coffee. Interested?

My point for posting this has nothing to do with coffee, or for that matter probability. I never would have found this if it wasn't for twitter. I have created a math feed on my tweetdeck and I find great stuff on here. Lots of garbage too. The formula above is from a post by AndrewEckford.

Why don't you give twitter and tweetdeck a try if you aren't already? You'll find it doesn't take a lot of time and you'll increase your opportunities to learn.

Power of Twitter: Add your name to the list please!

Matthew Arend retweeted this google doc . A teacher is using it to prove to their students the power of twitter. Have a look at it and see how many people have added their names. Add yours! I plan on showing my kids this. One of the nice things about a PLN is that sharing allows you to do amazing things like this. (To tell you the truth, I'm not sure who had the original idea! Guess I'm not yet totally twitterate)

I decided I would gather data for a presentation I am doing on higher order thinking in math and writing (or any other subject). I created my own google doc that I hope you look at and add the ways you ask your students to be knowledge producers in your classroom. Help me out with my presentation and pass it on!
