Classroom questions are the driving force to inspire students ’positive thinking, the key to open the students’ thinking gate, and the bridge to output information and timely feedback information. If the students ’brain is like a calm lake, then the teacher’s targeted and inspiring classroom questions are like throwing a stone into the pool of water, which can arouse the students’ thoughts and waves, open up the students ’hearts and develop students’ Thinking, so that students’ thinking at its best. Therefore, in mathematics teaching, teachers should ask questions from multiple angles, levels and aspects according to students ’cognitive level, teaching contents and class requirements, triggering students’ thinking, developing rich imagination, and improving the enthusiasm and flexibility of thinking And creative. First, grasp the question, triggering a positive thinking of students
