Watching the pretty awesome algebra2go video on conversions.   Here is my conundrum.   Okay, first that he goes rolling all the way through multi-step and multi-dimensional conversions in the same fell swoop, though that has its advantages, and  if I’m a teacher I can break it up — and a student could, too.   […]
