Tom Lehrer's tune, "New Math," sounds far too much for comfort like many public school districts’ math presentations.  But Lehrer was being sardonic.  It’s amazing we’re still dealing with defenders of constructivist math after all these years. 

Tom Lehrer recorded this performance in 1965.  Sometimes when one of the kids has brought home a math textbook, I have to revisit “New Math” to keep my sanity.   My dad had the vinyl album of That Was the Year that Was.  I think I was about ten years old when I started listening to it in the seventies. 

The richest line is at the 1:00 mark, though the line just before that is great too.  I like the part about making do with more primitive aids than a blackboard “as they say in the Ed biz.”
