1, Teaching Research of Number and Algebra: This topic can explore how to effectively teach the concepts of number and algebra in primary school mathematics, such as integer, fraction, decimal, proportion and percentage. We can study different teaching methods and strategies to help students understand these abstract concepts and improve their computing ability.
2. Teaching practice of Geometry and Graphics: This theme can pay attention to the contents of geometry and graphics in primary school mathematics, such as plane graphics, three-dimensional graphics and spatial concepts. We can explore how to help students establish a sense of space, understand the nature and characteristics of geometric figures and improve their geometric intuitive ability through practical activities, observation and measurement.
3. Cultivation of "problem solving and mathematical thinking": This theme can emphasize the importance of problem solving and mathematical thinking in primary school mathematics teaching. We can study how to design challenging questions, stimulate students' interest and curiosity, guide them to think and explore by using the mathematical knowledge they have learned, and cultivate their logical thinking, reasoning ability and innovative consciousness.
