1	The Famous Jinx Puzzle http://web.mac.com/ihor12/CMDB75/jinx Can you find a number that will jinx the Jinx puzzle? Use the Google Docs Spreadsheet to share your findings with others.
2	The Average Traveler http://web.mac.com/ihor12/CMDB75/TRIP/ Today we are going to find out who traveled the average distance to get to this workshop. First we'll start off with a guess. What do you think is the average distance that the members of this group traveled today?
3	Runner's Activity http://mathforum.org/tpow/print_puzzler.ehtml?puzzle=204 This example includes a software simulation of two runners along a track. The goal is to reach the tree at the same time. Students can control the speeds and starting points of the runners, watch the race, and examine a graph of the time-versus-distance relationship.

That's a 93.5% return on their initial investment. What was their secret of success? Having 150 shares of Apple stock which shot up through the roof in Round 10!
