Homework should be illegal: In many countries, we prohibit companies from making people work in their after work hours. In others, we shun the companies that do it and the people who take work home and work at the cost of their own resting hours. Its no different for children: Its extra work that eats up their private time. If something needs to be taught, it should be taught in the curriculum and anything that needs to be done should be done during the time that the classes are being given. If there isnt enough time to go through the entire curriculum, then it means the curriculum is badly designed and the children should not be made to spend their own private time to make up for it.
