Training students ’ability to calculate directly affects the formation and improvement of other maths ability, more importantly, it helps to promote the development of students’ creative thinking ability. Teachers should pay attention to cultivating students’ computing ability, helping students to understand the calculation of computing, seeking a reasonable and concise calculation process to solve the problem, and to believe that every student has the ability to find and solve the problem by himself. Students calculate correctly according to the rules and the law of operation, and perceive the number, the quantity and the evaluation of the calculation results in order to further understand the meaning of the number in real life, understand the relationship between quantity in concrete situations and solve the practical problems in life.
