Teaching reflection:
In the process of preparing lessons and teaching, I teach with the main purpose of cultivating students' interest in learning mathematics, so that students can know that mathematics is inseparable from our lives, and let students feel the relationship between numbers and our lives in activities, thus guiding students to grow, discover, learn and use numbers.
