The school policy is to give homework between 20-40 every night. I really don't believe it Is necessary and on the contrary I feel it builds resentment towards the learning. I work a whole day to motivate the boys to learn, enjoy their learning, and I blow it with homework.  if there was a reason for me to believe they are gaining extra skills of knowledge I may be ok with it but I don't see any significant difference at all. May parents think it is one of the Aseres Hadibros and I should never skip it. What is the best approach?
