Homework is an assignment that students are given to do at home. It might be a continuation of classwork or a new piece of work. It may also be preparation for the next class. The amount of homework school students get varies a lot not only from country to country, or from school to school, but often from day to day. For most the amount of time spent on homework gets longer as we go through our school lives. At the start of primary school we get almost no homework but it is often several hours a day by the time we finish secondary school.
