Homework is an important part and extension of classroom teaching. Homework is not only a way for teachers to understand students, but also a way to train students' thinking and cultivate their ability. However, for a long time, people tend to position the function of homework on "consolidating knowledge" and "strengthening skills", which leads to the misunderstanding that homework questions are dull, monotonous in form and closed in content. It makes students lose enthusiasm for homework and turn it into "completion", which seriously restricts students' thinking and potential development and runs counter to today's educational policy. Today, with the full implementation of quality education, teachers should start with students, the main body of homework, so that students want to do homework and are willing to do it, thus improving students' learning desire. Therefore, when designing homework, we should not only design homework on the premise of being interesting, practical and open, but also guide students to exert their potential through creative homework activities, so that homework can become a sky for students to release their thinking and potential. The amount of homework should be moderate, so as to ensure that the students' writing is standardized and the difficulty is just right, so that poor students can do it, good students can master it more skillfully, exercise their will, cultivate their ability to do things independently, and finally improve their academic performance.
