Isn't That Odd?

BatBoy has been exploring odd and even numbers for awhile, just categorizing them in his head and finding patterns.  He came to a conclusion a month or two ago that odd numbers had 'middles' and even numbers didn't.  I've tossed in the idea lately that the pieces of even numbers can be paired off; in essence, they are divisible by two.  But, that didn't (yet) disagree with the 'middles' theory and BatBoy seemed to disregard it.  In the past week, however, BatBoy has encountered two troubling numbers:  zero and one.

Having embraced the idea that my kids are pretty right-brained when it comes to learning math, I feel more comfortable introducing problems that would normally be several "steps" ahead of where they are.  Enter into our lives:  the Maths Quest series by David Glover. 



The Museum of Mysteries focuses on number manipulation.

Many Paths to an Endpoint

When I was in university, I had a professor for a geometry course that all math teachers were required to take.  I found it interesting at the time that he was a professor that students seems to really like or really dislike, in terms of teaching style.  At the time, I chalked it up to his habit of bringing in ideas and skills from related courses, and the lack of good mathematical understanding by some students, which, I thought, should allow them to integrate the different areas of mathematics.
