The Age Game

This puzzle features a series of computations involving, among other factors, the student's own age and birth month. After the computations are completed, students are asked to find a pattern in their answers. This is best done in groups and is not difficult if no computational errors have been made. After students have discovered the pattern they can confound unsuspecting friends by telling them their ages and birth months if the the friends share the same results of the same computational process.

The real challenge in this puzzle, however, is to find out why it works. We hope that you will give this month's puzzle a try.
