On the first day of class in AP Calculus and Pre-Calculus Honors I’ll give out the following list of puzzlers that they’ll have a limited amount of time to work on. The students will be working in groups on the new $2 interactive whiteboards.
Btw, I still haven’t figured out the pentagram puzzler. Maybe they’ll beat me to it!
Is this the sort of thing that you give them day in and day out?
Not every day, but quite often. I give them Car Talk puzzlers when there are good ones, and if I come upon other puzzlers then I like to throw them out too. It depends on the class. Some classes love them, some not so much.
Nice! Really liked these for the older students. The pentagram isn’t as hard as you think; it’s a question of how you count…Cheers!
We didn’t count overlapping triangles because if you do then you’d start with far more than 5 triangles. A student did find a solution that got 10 non-overlapping triangles.
