Generally speaking, this paper has listed all the knowledge points of this book, and the summary is comprehensive, moderately difficult and solid.
One: Test paper analysis
First of all, the size of the number is more important in the comparison between the calculation problem and the size of the number, which involves the comparison of decimal numbers in the fourth unit module. For example, there is a comparison between a number in units of "10,000" and "100 million" and an eight-digit number. When students are older, it is easy to ignore the score, which leads to inaccurate digital readings and errors. Secondly, when the unit is "ten thousand", it is not clear whether it is an estimated value or an accurate value. Calculation problems are mainly simple calculations. There are two reasons for the error: the first reason is that there is an error in the calculation data itself; The second reason is that the operation rules are wrong. In the simple calculation, some students are not careful in reviewing the questions, so they can't reasonably arrange appropriate operation rules for simple calculation.
Two: improvement measures:
For this paper, the first negligence in the review stage lies in the lack of attention to calculation. In fact, students have a clear grasp of basic arithmetic and operation rules, but they can't use them flexibly and lack some targeted intensive exercises.
Second, in the usual practice, the cultivation of students' ability to analyze problems, extract data and organize information is not paid enough attention. For example, when children look at the questions, they often can't see the questions clearly over and over again, which leads to mistakes in the exercises. On this basis, teachers should pay attention to children's usual behavior habits and pay attention to positive reinforcement in general teaching. Give timely affirmation to some good behaviors of children.
