As a teacher, we must first know how to learn math well. If teachers don't know how to learn math well, how can they promote math learning? If we don't know where the key factors hinder mathematics, then mathematics teaching will become blind and divorced from students. Therefore, teachers should be able to find out how to learn mathematics from their own learning experience and use these methods to help students learn.

Being good at understanding students is also a necessary quality for teachers, which means that teachers should be good at spying on students' knowledge background, thoughts and hobbies through observation, inquiry, analysis of homework and investigation, so as to understand students' "mathematical reality". Only by recognizing students' difficulties and knowing ourselves and ourselves can students cooperate with each other and have a positive reaction to mathematics; Understanding students' ability also includes timely feedback in class, adjusting teaching according to the obtained information, and understanding the effect of students' learning after class, so as to check whether the teaching objectives have been achieved and prepare for the new teaching.

Good interest is a good teacher in learning mathematics, and it is also essential to cultivate students' thinking and habits in mathematics learning in teaching. For example, when I teach the knowledge of cuboids, I creatively use teaching materials to let students understand the basic ideas and methods of learning three-dimensional graphics while describing the characteristics of cuboids with standardized mathematical language. For the understanding of 3D graphics, we should follow the principles of whole before part, intuition before abstraction, make full use of the physical objects and models of 3D graphics, intuitively perceive the whole first, and then abstract the relevant features, so as to help students form the basic ideas for the research of 3D graphics.

Geometer's Sketchpad is an excellent professional teaching platform software. The software is short and powerful, and can dynamically express the relationship between related objects. The main clients are math and physics teachers, and users can make professional teaching courseware through geometry sketchpad. Geometric sketchpad is one of the best teaching software.

Being able to make courseware is one of the three necessary conditions for becoming an excellent math teacher. In mathematics, many abstract teaching contents must be completed with the help of auxiliary tools. If the school can't provide courseware suitable for lectures, the teaching effect can only be achieved by making it yourself. The geometric sketchpad mentioned above is the most effective assistant for making math courseware, and math teachers can use it to give full play to their creativity and make their own ingenious courseware.
