Expanding knowledge points: how to learn second-grade mathematics well?
For calculation problems, some students start with a pen, and the calculation is monotonous and boring, which may cause psychological fatigue. When they encounter similar or similar numbers and symbols, they often have errors in operation order, symbols or data. Still lack of good calculation habits, especially after students learn mixed operations, the order is unclear. Therefore, in the teaching process, students should be trained to carefully examine the questions, see clearly every data and operation symbol in the questions, and then calculate. Carefully examine the questions, grasp the key words, find out the known conditions, carefully analyze and read each question at least twice before you can work it out.
