The rule suggests that students should be assigned no more than ten minutes of homework for each grade in school. To use this guideline effectively, the teachers in a school must coordinate so that each subject shares in contributing to the recommended maximum. For example, if a student in grade ten had five daily courses, each teacher might assign a maximum of 20 minutes of homework. If one teacher ignores coordination and gives an hour of homework, the demands on a student can get unreasonable. There are many other policies that can keep homework reasonable.
Sensitive coordination is the key to a reasonable use of the value of homework.
This reasonable use recognizes that young people need time to learn and grow and relax separately from school activities.
