Doing math homework with my eldest son brings back my math club experience from public school.
I was a bit of a math geek in school and it has helped me in life. Math is such a critically important skill to master. My eldest son's teacher is taking his Masters in Math at the University of Waterloo and is a true math head. He assigns so much math homework it is somewhat overwhelming. The obvious upside is that my son is learning math cold.
Thankfully the internet is available to remind me what a T chart is...
