This paper is divided into three parts: basic questions, calculation questions and problem solving.

Among the basic questions, fill-in-the-blank questions and multiple-choice questions have better answers, and individual students lose points; There are many students who have misjudged the second question. This is a conceptual topic. Students do not have a solid grasp of concepts and need to consolidate basic knowledge.

Calculation topics include oral calculation, vertical calculation and parting calculation. Most students can get full marks, but some students make mistakes in the estimation of oral calculation. It seems that the practice of estimation needs to be strengthened.

Solve problems, including operational problems and application problems. The operation question examines students' practical ability, and there are fewer mistakes in this question; In the application questions, the third question and the fifth question, some students did not look at the questions carefully and did not understand the meaning of the questions, which led to mistakes in blind calculation.

Passing this exam has already reflected some problems. In the future, we should carry out various exercises where there are problems to help students improve their grades.
