The ignorance around math is amazing to me. When I went to a public school in NYC in the 80s, I had 1960s textbooks and a pretty poor initial math literacy — I struggled into middle school.

When I look at the common core stuff with my young son, he gets what he’s doing in a more fundamental way. In first grade, he basically “discovered” division on his own and was incredibly happy about it. Not something I would have done for sure!
