Last week I started throwing a little extra math into my classes, homeroom and last period (homeroom students again) - by using the date! I went to a conference years ago and this was one of the ideas in the book we were given.
I haven't used the idea in a while, so I brought it back in two ways:
1) Use all the digits in the date to create an equation. The digits should stay in the same order they are in the date, and any operation signs can be added in between any digits. The equal sign can also be placed between any digits.
Digits can be used as exponents, as in the example shown, and you could add square roots signs if you can find a way to use them.
2) The other way I used the dates was to write the date so that students have to solve an expression for each number in the date.
It's been fun to see some students writing these in the corner of their notebooks during class! Others have asked to write their equations on the board during the last period of the day.
I'm looking at the date-writing as another way to introduce notation my students haven't seen before, like the cube root.... I loved today's date!
How would you write some of these dates?
