text: The first reason that teacher should assign the summer assignment is because it provides a challenge to the students. If the students were gonna design the assignment they would make it easy so they wouldn't have to put much effort into doing the work. If the teacher designed the assignment it would require hard work and more effort and time in completing the assignment. They won't be preposterous, just hard enough so that a challenge is provided. Giving the students challenging summer assignments would get them ready to take the class they are taking next year.
