It's Not About the Answer… It's About the Process
Yes, more of this!!!!
This teacher has students do a non-routine problem solving activity. This is not about doing something the "right" way or even about getting the answer! We need students to have interesting problems to challenge them and make them think. After all, it's not really a "problem" if you can solve it in 5 seconds!
If you want your students to have some non-routine problems to try, check out Problems of the Month. I try doing these once per unit.
