Puzzles for 11.11.11

Some questions we are asking our classes today:

Anand: How many times this millenium will the date consist of a single digit?

Bill: Today, the day, month, and year are the same. In how many days will this happen again?

Angela: How can you get an answer of 0.0909090909… using only one number, but as many times as you want, and basic arithmetic?

What are you all doing?

our text

We've written a curriculum for 9th-11th grade, based on mathematical habits of mind and the idea that learning math should be about problem solving rather than rote procedures. This text is freely available. Read more.
about us

We are members of the upper school math department of the Park School of Baltimore. This site is meant to be a place for us to discuss our teaching lives with each other and (hopefully) with you. We believe that the more conversation, the better. And that talking about teaching mathematics can be almost as much fun as teaching it.
