This should be chosen according to the actual situation of students. For example, if your students' basic knowledge is weak, choose to practice every day; If the basic knowledge is good, but only the examination of questions or careful calculation is not serious, then choose Stickmen. If the basic knowledge is solid and the questions are done seriously, such students are masters of learning. They can find some difficult and expansive topics to do, which can stimulate children's interest in learning, gain a sense of accomplishment and increase their self-confidence.
