After all of the Math Mondays I have done this year, this post is the last. Writing about math every Monday has not really helped me with math, but it has helped me learn some new things about math. That is because these topics come from the pre-algebra teachers, and I am in algebra so I don't know everything that is taught in pre-algebra. On some of the post topics I have had to do research such as on the post about Pi. 


Next year we are starting a new thing called Common Core. This is a new system for how we test and all of that stuff. Common Core includes a lot more writing. This includes math, so we will have to answer more written problems. I think math Mondays should have prepared me for that a little bit, so maybe I did learn something from my math Monday blogs this year.

This is something I have always wondered, but never actually took the time to figure out. Today I looked this up on the internet and from what I have found, there are about 100,000 to 150,000 hairs on the human head depending on what hair color you have. Some websites that I used to find this information were http://bionumbers.hms.harvard.edu/bionumber.aspx?s=n&id=101509&ver=2
and http://mathforum.org/library/drmath/view/61887.html. 

But I also wanted to find out how to do this using math. The way that I figured out how to do this was to first find the surface area of my head.  Next I would have to measure off a fraction of my head and find out how many hairs are in that part of my head. Next I would find out how many of those sections of hair would fit within the surface area of my head. Then I would multiply that number by the number of hairs in one section to finally find out the total number of hairs
