The mathematics problem scenario is an important source for students to acquire knowledge, develop innovative consciousness, and develop psychological quality. The principle of problem scenario creation must follow the principles of enlightenment guidance, intuitiveness, timely feedback, and theory connection with practice; the key to creating problem scenarios is selecting new ones. At the entry point of knowledge, design issues must have gradients and coherence that can arouse the attention of students and a good emotional experience. Through the occurrence of design concepts, the expansion process creates problem scenarios; creates variant problem scenarios, and excavates and expands examples (exercise questions) to cultivate students’ broad thinking.
