I guess what I should say is - Do you make your kids do the "extra" practice sheets/"Try this at home" stuff. My DD is in 1st grade and there are only two real homework assignments they have to turn in each week: Math Worksheets and Reading Logs.
Yes, I make her do the assignments that need to be turned in, but then there are other "assignments" that don't need to be turned in. Some of them are spelling practice and the others are practicing some sort of Math triangle formulas (from the Everyday Math curriculum). I don't make her do these. I never made her do these because I know she doesn't need the practice. I have never even discussed them with her.
Well, the other day, she came up to me, plopped down the math fact triangles and said "I'm NOT doing these. This is dumb! It's stupid to practice these when I already know them!"
