Games have begun and there have been several upsets but March Madness won't be over until the finals on April 3rd and 4th. March Madness bracket predictions can still be reworked.

This year there will are 68 men's and 64 women's college basketball teams in the tournaments.

If you try to predict how the games will play out by filling out a bracket, what are your chances of picking every game? How does the change from 64 to 65 to now, 68 teams in the field complicate things?  How many brackets would you need to fill out to pick every possibility?

March Madness – Does seeding really matter?

Always updated!
March Madness, the big 68 team college basketball tournament, will now take over our TV viewing during the weekends of March. School and office friends are filling out brackets.  Engage your students in percents as they get excited about March Madness. Is getting a higher seed really an advantage?  Use 30 years of data to help determine for which seeds it makes sense to pick an upset.  Finally, students determine a general strategy for picking games in the first round.
