3. Geometry: Geometry is an important content in mathematics, including plane graphics and three-dimensional graphics. Students may be confused about the names, properties and calculation methods of various geometric figures.
4. Data statistics: Data statistics is an important skill in mathematics, and students need to learn to collect, sort out and analyze data. They may be confused about how to make tables, charts, bar charts and other statistical tools.
5. Problem solving: Mathematical problem solving is an important link to cultivate students' logical thinking and problem solving ability. Students may be confused about how to analyze problems and choose appropriate methods and strategies.
In order to help students overcome these difficulties, teachers can adopt various teaching methods, such as explaining concepts through real-life examples, providing rich opportunities for practice and practice, encouraging students to cooperate and discuss with each other, and giving timely feedback and guidance. In addition, parents can provide extra support and counseling at home to help children understand and master mathematics knowledge.
