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? How many reams of paper would you need to print all of those brackets? Let’s do the math! Also, check out the video below that explores your odds of picking all games in the tournament perfectly.
The Cricket World Cup is being played now in Australia and New Zealand. This is a complex game that seems to be played with enthusiasm and humor. In this activity students learn about the game; watch a couple of videos on how it is played; calculate the number of matches that must be played; try to reason how to count the matches in a more abstract manner; and decide whether the unusual organization of the matches seems fair. Tons of good math while learning more about this worldwide game!
Green, green river - During the St. Patrick's Day parade in Chicago, the local plumbers" uniondyes the Chicago River emerald green. Students learn what PPM (parts per million) means and attempt to figure out how much dye is used to sufficiently color the river.

The Iditarod dog sled race begins officially in Anchorage, Alaska on March 7th and then restarts in Fairbanks two days later. There is so much mathematics in this race that our activity feels totally insufficient. Mushers and their dog teams travel by day and night and, in their quest to win, have very little time to rest. But, perhaps the activity will raise interest and encourage students to find out more and bring their research to class.
We've dealt with reading charts, calculating speed, calculating present value, and considering daylight hours of travel.
But, who will win? With how many dogs left? After how many days? Through what conditions? Through what mishaps and challenges? The list goes on ...
