Tues Sept 21 - a devilishly good class

Today we corrected the divisibility rules (blue sheet) and began reading one of Ms. Gesner's favourite works of Math-inspired fiction - The Number Devil by Hans Magnus Enzenberger.
http://www.amazon.com/Number-Devil-Mathematical-Adventure/dp/0805062998#reader_0805062998

The Number Devil illustrated the following Math facts:
1. Any number can be found by adding up 1s (1+1+1+1)
2. There are therefore an infinite number of whole numbers (because you can always add 1 more)
3. There is an infinite number of numbers between 0 and 1, and these numbers become infinitely small (picture splitting a piece of gum over, and over, and over... although with gum you might eventually get a sub-atomic particle that cannot be split...)

Homework:
None!
