Maybe public schools have become the employer of last resort while talented people found jobs however menial, elsewhere. Every teacher I talk to hardly speaks English. One told me she cannot balance a checkbook.That is why she teaches “math”. Have we sunk this far?
Teachers, in general, are bad at math
That “math teacher” has an education back ground, they suck
The best math teachers are the ones that came from industry. Not only do they know math, they also can demonstrate how it can be used.
