If you roll a die two times in a row, what are the chances that you will get at least one 1?
What if you roll 3 times? 4 times? "n" times?
Afterwards, we talked about ways the group worked well together, ways they didn't work well together, and we identified the habits/strategies that were useful for each group. There were a lot of amazing things that happened and some really great discussion that followed. Mostly, I loved that the students had to (and did) push, challenge, and support each other in an attempt to justify their solution and prove to each other that it made sense.
I was left wondering:
1. Why doesn't this work as well with a WHOLE class discussion/collaboration? What would support that? I think this post and research might help....haven't read it yet.
2. Does this collaboration happen with small groups also? It's harder to tell when you are monitoring multiple groups.
