1, teaching content: learning and thinking, calculation and migration breakthrough focuses on the training of basic mathematical knowledge and operational skills, including addition, subtraction, multiplication and division, fractions, decimals, percentages, etc. , and pay attention to cultivating students' calculation speed and accuracy. Learning advanced calculation is to further expand mathematical thinking and problem-solving ability on the basis of basic mathematical knowledge, including algebra, geometry, probability and so on. To cultivate students' problem-solving ability and innovative thinking.

2. Teaching methods: learn and think, and turn to calculation. By using a large number of exercises and calculation exercises, students' calculation ability is improved through repeated training, and the mastery of memory and operation skills is emphasized. Advanced Computing, which focuses on learning while thinking, focuses on cultivating students' mathematical thinking and problem-solving ability. Through heuristic teaching and the application of practical problems, students' innovative thinking and problem-solving ability are cultivated, so that students can face more practical problems more easily.
