Hello everyone! In preparation for Pi Day, I've created this very simple PPT for us to use FREE of charge. At our school, we have a contest in which students recite as many digits of pi as possible. But there is one catch: instead of saying a string of digits at once, students take turns saying ONE digit at a time until someone makes a mistake. If student A says a digit incorrectly, student B can eliminate him/her by saying the correct digit and the subsequent digit. During the competition, this PPT is projected so that everyone (other than participants) can see it. I use a wireless mouse to click on the slide as each digit is read so that the audience can see how many digits have been memorized (a total is calculated with each click). Enjoy and I'd love to hear feedback! Happy Pi Day!
