Didgets of PI you know?

Question

How many disgets of PI do you know.

Answer 1

Hello

I am a high school math teacher and the only extra credit I offer is memorizing pi. So you get 5 points for 20 digits, 10 points for 40 digits and so on. (y = .25x is the equation I use when the student memorize hundreds of digits).

I teach all my classes the first 20 digits of pi on the first day of school. I told them that I can teach 90% of them 20 digits of pi in 2 minutes and 60% of them will retain it for the whole school year. So far at the end point in the school year - about 70% of the students can still recite pi to 20 digits. I use a very creative song and dance routine.

Many of my students have memorized 100, 120, 140 digits. Then I had a D- student who was ready to turn 16. Her parents said that she couldn't get a car unless she got a B in Math. So she spent a few nights memorizing pi and she stated 242 digits outloud to the class with no mistakes and no more than a 3 second pause.

Hope this helps

By the way, the world record for reciting digits of pi continuously without a mistake is over 60,000.
