Is it possible that the teacher has quite poor number sense, and doesn't really understand what they are doing?
Honestly, this was my first thought. But I must admit to being a bit nervous around these H.S. teachers. They are (thankfully) a nice step up from the M.S. staff and I know they are even less interested in hearing boo from parents. So, as I already have a tendency to do, I'm over-thinking this. I just don't want to be labelled this early in the year!
I thought about waiting until the semester, but at that point my saying anything looks a lot more like trying to change a grading decision after-the-fact to benefit my son.
