So my son just failed a math test, even though his math was correct because the teacher had a different opinion about how it should be solved.
Don’t blame the teacher. Blame the common core. Poor math teachers. They’re really feeling the pain of the CCSS
And where exactly is the CCSS prescriptive as to methods? If anything the standards for mathematical practice actively encourage students to pursue many and different solution paths. Are you thinking of the few standards on fluently using the standard algorithms?
I won’t pretend to be an expert on the math standards and I’m sorry If I’m wrong. All I know is that the math dept in my district ( and I am not in the dept so I only know second hand) has very specific rubrics about how students have to solve specific problems. Maybe this is just my district, so i should be careful about generalizing— apologies.
