Real Number Beer Pong (Extra Credit)

**although not for public school consumption, this is a very neat activity by one of my college students**

More Real Number Extra Credit

I'm a sucker for the real number system :) I love offering extra credit for this topic. Here is a cute idea based on a theme I did many posts ago titled "Pin The Tail On The Real Number Donkey". A student of mine had the same idea and her donkey looks better than mine. The only flaw is that her 'irrational' circle is mixed with the other 'rational' circle. It's still a cute project though!

Making Use of Old Phone Books

Old phone books may still offer some mathematics educational value.

 

It has plenty of built in subtraction problems

Another project would be to weigh the phone book and calculate the approximate weight of all the phone books in your area. You could even assign an approx cost if you research materials.

But, of all these, the best exercise for authentic learning I can think of is to simply ask your students what we could do with all these phone books? How could they be used in education?
