This is an idea for a bulletin board using the MLB playoffs. Download the playoff bracket and print one for each student. I found mine on my MLB@Bat app on my iPad. You need to do this right away since the playoffs start the next day. Have each student predict who will win each round. Offer a cash prize for anybody who gets a perfect paper (don't worry...there is a 1/512 chance of a perfect paper).
Display and update the papers as the playoffs progress.
Math ideas we discussed:
-After the first game we discussed how many people already missed a game. We compared theoretical vs experimental probability.
-After the second game we discussed again.
-After the sixth game I had one entry left with all the games right. We discussed the theoretical probability of getting this far with a perfect entry and the probability of finishing with a perfect entry.
-After the playoffs I displayed the entries as a frequency distribution. We discussed normal distribution, uniform distribution, skew, and symmetrical.
One tip: Make sure you have 8, 16, 32, 64, or 128 entries. It makes it easier to analyze the probabilities. If you have to use 'coin flip' entries to fill out the field. I had to use one coin flip entry to get to 32 entries. It was the only one to pick Cleveland in the 2016 World Series.
