## Great Classroom Action

January 17th, 2013 by Dan Meyer

**Avery Pickford’s** Truly Group Project:

So our crazy new idea? We’ve put together four open ended, challenging probability games. Eight groups of 3 or 4 will spend tomorrow working on one of these games (2 groups for each game in each class). On Tuesday, groups will rotate and work on a different game, starting where the previous group left off.

**Mr. Owen’s** amazing work with ActivePrompt:

Since that was too easy, I next told them to create two more parallel lines that were neither vertical nor horizontal. They pretty quickly realized that it was all about slope. Their idea was to assign everyone a number and then have them go up and over by that amount (1,1) (2,2) (3,3). The real genius idea (only one class did it this way) was to translate that first line up using the rule (x , y) –> (x , y+1).

I originally figured the “create two parallel lines” ActivePrompt to be a great team building activity and little more. Mr. Owen’s class completely surprised me. Must read.

**Kyle Pearce’s** Detention Buy-Out:

In the video, three administrators from Tecumseh Vista Academy K-12 School are interviewed and propose individual options for students to avoid serving detentions by paying the administrators according to their buy-out offers.

**Julie Reulbach’s** Barbie Bungee jump:

There is nothing more exciting then seeing seeing if your Barbie is going to come crashing to the ground. The students learned so much and we ALL had a blast!

Watch the clip. Get excited about how excited kids are to see the results of their calculations verified outside of the textbook’s answer key.

My Algebra class worked on the detention buy out problem today, and they loved it. The discussions were great, and the students did not even realize they were using Algebra.

Thanks so much for getting Barbie Bungee out to more math teachers by sharing my blog! It was the most exciting lesson I have ever taught and the kids loved it. It has changed the way I want to connect with students. I want them to live the math as they learn it!

Glad you and your class enjoyed the Detention Buy-Out, Andy! I need to get back on the horse and start thinking of another problem we can get the kids working on!
