Tomorrow is my last day of Geometry End of Instruction exams. This week has gone so quickly with block scheduling! On the positive side, my Geometry students said they felt prepared for the exam. Since we did not have official "review" time, that made me feel a bit better about the week. Of course, from many years as a teacher, I also know that "feeling good" does not translate to high scores! LOL
I had planned to test in my AP Stat class, but with only 6 more class sessions until the AP exam, I decided that I would rather do an activity. Bonus - no grading!!! wooohoooo!! hehe. Looking around my room, I had some left over M&Ms and remembered seeing an AP review activity on Mrs. Smart's website. I started with her idea and tweaked it to fill up a 2 hour review session for various inference methods. Since I typed this up tonight (after a 2 hour nap), it's still pretty rough, so please excuse any typos. :)
Everything I learned about Inference...
The end is in sight! One month left at the HS - only the final left at the Uni... where, oh where did the semester go???
Update: This activity went extemely well!!! The kiddos were actively discussing the problems and stayed engaged for 2 hours - excellent :)

Melts in your Mouth... Not in your Hands :)
Everything I learned in Stat class, I learned from M&Ms :)
Some days, that statement feels so true. From univariate data (weights of bags, proportion of colors), to probability, and finally to inference, most topics in Intro Stat can be related back to M&Ms.
This week at the Uni level, we will delve into inference for proportions. As my Uni students have already figured out, I much prefer using real data to just putting problems on the board and droning on and on :) This week we will learn to do confidence intervals and hypothesis tests using M&Ms.
M&M Activity Sheet
At the HS level, when we covered this information, I chose not to do M&Ms and instead did a "globe toss" using a blow-up globe from Oriental Trading company. The students had a lot of fun tossing the globe around in the commons area and using the data generated to learn how to do a CI and HT for proportions. To top off the chapter, I gave a quiz a few days later. With the quiz, they each got a bag of Skittles and had to do the CI and HT for their bag. While it was a pain to grade, the kids enjoyed eating their quiz data :)

On a different note, I have no idea how many people have actually read this blog (other than Jackie - my lone commenter *grin*), so I don't know if the material I am posting has been useful to anyone out there or not. The AP Statistics community is fairly small and mostly rely on the ap-stat listserv to communicate with the other Stat teachers out there. However, I have found it rather interesting to post my lessons and commentary for my own documentation if nothing else. By updating the posts with what worked and what needs to be modified, I am hoping to use this like a journal as I teach the same lessons next year, tweaking and improving as I go.
