In the "reading subjects" such as history, science and literature, homework is given for the purpose of preview of the material the teacher will teach the following day. There are usually a few pages assigned to read and then a few questions to answer. Aaron has to answer in a complete sentence so that it is clear what the question was, and also what the answer is. If the assignments are approached in this manner, every assignment becomes a great review sheet.
This preview of material helps to lay the foundation on which the teacher will build on in class the next day. It is an important part of the learning process, and if you try to bypass the homework, your child will not grasp the material as well as they should.
In the "skill subjects" such as English and math, homework is given for practice. After the concept was taught in class, students are assigned homework problems to "practice" and to further develop the "skill" taught.
Homework is beneficial and an important part of the learning process. It is important to check homework to keep students accountable for their learning.
