If excessive homework is cutting too much into the time needed for children to complete chores, should concerned parents suggest to the teachers that less homework be set?
I guess it depends on your priorities.
For me, it would be allowing my children to get the best education possible. So I would back off on the chores and encourage more homework.
My children knew that if their teachers didn’t give them enough school work to do, I would find more homework for them. I didn’t have children to have ready made housekeepers. That was my job. While they did have their chores to do, they were mostly as a learning experience not to have a clean house.
