- Riley Lark expresses angst on the difficulty of teaching probability, and then offers up the Monty Hall problem, with candy.
- Bowen Kerins talks about game shows. He also develops that stuff into some really fun PCMI problems.
- Chris Lusto helpfully inverts the traditional sequencing of some of the combinatorics material. And he patiently explains what makes this stuff so hard to model, but still urges us to find some way to model probabilities for students.
- Dan Meyer's got a great idea for an expected value activity that simmers for weeks before it's ready.
All that I have of my own is a couple of very rough ideas for three-act problems on 101qs, but neither seems to be doing particularly well.
My job for the next few nights is to remix this stuff into something coherent. If you've got more resources, I'd love to see them. Toss them into the comments, if you don't mind.

Update:
- I bought 100 dice for about 20 bucks so that we can do some simulations in class.
- I like Plinko. Here's my Act One, and Bowen's slides from NCTM contain a good idea for Act Two. Here's how he develops it in the PCMI problem sets from 2007:
