10 to 20 minutes of homework? Good grief. I wanted my kids to have homework, and I wanted to see what they were working on....so I could deprogram them as needed and show them the right way to do it.
We were not able to homeschool, but we had various ways to know what was being fed to them (including my wife working as a sub). I think if I still had young children in school we would work out a way to homeschool.
10 to 20 minutes doesn’t sound like much, but I’m not sure a first-grader who is all of six years old really needs it. At that age they’re still learning to read, and can probably barely write.
