I. Background Introduction The students who attend the lectures are students of the vocational high arts class. Their learning base is relatively poor. Especially for mathematics, most students have low interest. Only a small number of students have a certain foundation and desire for further improvement. However, these students Being active, open-minded, strong in execution, and enthusiastic, once excited to their point of interest, they have endless stamina, which has a great role in promoting teaching. Design Intent: Inspire mathematics problems with mathematics, use more with less, use activities with teaching, and mathematics with mathematical thinking. Classroom effect: This class was very successful overall, using the collection of this math problem, triggered
