New Insights and New implications

First of all my new insight is that I am not good with google docs, it took me 40 minutes to figure how to post this. On a mathematical topic, i found out that just because i knew the rule to something did not mean that i knew the reason for the rule. Many kids do ask 'why' in school and they are shunned by their teacher with a simple answer that has no meaning which is 'because I said so' I am also finding out that as I go through the class I get more and more frustrated because it forces me to think aside from the rule that was rudely inserted in me as I learned math. One thing that I found interesting in class today was the reason as to 'why' when we are dividing fractions we 'flip' the second fraction and multiply across. I had NOOO idea the reason why, and it always bothered me, but know I understand and I feel as if I could explain to that 'why' child the reason as to why that rule is set up.
