Homework, or a homework assignment.

“Is a set of tasks assigned to students by their teachers to be completed outside the class. Common homework assignments may include a quantity or period of reading to be performed, writing or typing to be completed, math problems to be solved, material to be reviewed before a test, or other skills to be practiced.”

“The effect of homework is debated. Generally speaking, homework does not improve academic performance among children and may improve academic skills among older students. It also creates stress for students and their parents and reduces the amount of time that students could spend outdoors, exercising, playing sports, working, sleeping or in other activities.”
