I’m mystified by your complaints. What curriculum are your schools using? Is it the fault of the curriculum or the teacher misusing the curriculum? Can you give a sample of the incoherent problems they’re sending home?
I’m a mathematician, and have an interest in the K-12 schools not mathematically abusing children either with drill-and-kill that might get them to do arithmetic decently, but will make them hate math, or with the fluff that math ed types in colleges of education have been foisting on us of late, which leaves them innumerate (and usually even more math-phobic).
As I offered to Hodar, I will offer to you . . . I will check to see if my granddaughter still has any of the math homework worksheets from last year and provide some examples. I won’t be home until Friday, and in case I forget by then, ping me to remind me about this.
