Mathematical methods are permeated with a natural scientific theory, and students can learn more about mathematics by making some handwritten newspapers. The following is the design of the fifth-grade math tabloid I shared, I hope it will be useful to you.

Introduction to abacus calculation of fifth-grade mathematics tabloid pictures and mathematics tabloid data

1. Calculus as a checking tool

When learning three-digit addition and subtraction, the children made it clear through discussion that every calculation problem should be checked, because through checking, they can know whether the calculation is correct, find their own mistakes, and correct them before the teacher corrects them.

What are the inspection methods? If vertical calculation is adopted, it means recalculating according to the original formula first, and then calculating according to the relationship between the parts of addition or subtraction, including checking addition with addition, checking addition with subtraction, checking subtraction with subtraction, and checking subtraction with addition.

Is there any other way? The children who learn abacus mental arithmetic told me in unison: teacher, we can do it again with an abacus to test whether the calculation is correct. What a great idea! From then on, whether the teacher wants it or not, the children will put the abacus on the table, keep it at hand and use it at any time. The frequency of use is high, but the phenomenon that the abacus is squeezed off the ground is less. In the end, I will no longer worry about the impact of abacus falling off on normal classroom teaching.

2. abacus as a recording tool

When recording data, in order to make children realize the necessity of recording data by drawing orthography or graphics, I changed to listening to data recording. The specific teaching process is as follows:

Teacher: There is a class with 37 students, just like us. How many boys and girls are there? I don't know, but I can report it to you. Please make a record.

The teacher began to report boys and girls. Students listen to the tape. After applying several times like this, the application speed was accelerated, and some students began to * * *: Teacher, you applied too fast! We don't even remember!

then what Is there any good way to help us record information quickly and well?

A child said, we can write down the word male and female first, then the teacher will report a male, draw a vertical line under the male, and the teacher will report a female and draw a vertical line under the female.

Oh, you can divide men and women first, and then draw vertical lines to record the data. Is there any other way?

The main way to learn mathematics well is to cultivate students' mathematical rigor ideologically. There are often many junior one students who don't pay attention to the rigor of mathematics and think that finding the correct answer is enough, regardless of the calculation or reasoning process. Over time, students have developed a bad habit, which has a bad influence on their future mathematics study. Stiffness is the basic feature of mathematical theory, which requires that the expression of mathematical conclusions must be accurate and concise, and the reasoning and argumentation of conclusions should be well-founded step by step and meet the reasoning requirements everywhere. Considering students' understanding ability and characteristics, we can appropriately reduce the rigor of middle school mathematics teaching content, but we must ensure that students have a correct understanding and mastery of the corresponding teaching content. Gradually cultivate and develop students' logical thinking ability.

Secondly, in form, we should cultivate students' abstract thinking. The content of primary school mathematics textbooks is popular and concrete, while the content of junior high school mathematics learning is abstract. It studies the transformation of letters, equations and figures. Pay attention to both calculation and simple proof, which increases the difficulty compared with primary school. In primary schools, due to the lack of teaching content, there are plenty of class hours. Therefore, the class capacity is small, the progress is slow, and there is enough time to repeatedly emphasize the important and difficult contents. The teacher has time to demonstrate the solutions of various exercises. Students also have enough time to consolidate. Due to the increase of knowledge points, many subjects, increased flexibility, large class capacity and rapid progress in junior high school. This also makes freshmen unable to adapt to junior high school mathematics learning, so cultivating students' abstract thinking is conducive to adapting to junior high school mathematics learning more quickly.

Thirdly, in learning methods, we should cultivate students' ability to draw inferences from others. In primary school, teachers talk in detail and practice more. In the exam, students can generally get good grades as long as they remember the concepts, formulas and example types mentioned by the teacher. Therefore, students are used to turning around the teacher, not paying attention to independent thinking and law induction. In junior high school, because there is too much content and too little time, the teacher can't talk about it in detail, but can only talk about some specific and typical topics. Therefore, students are required to be diligent in thinking, be good at summing up laws and master teaching thinking methods. However, for freshmen, the learning methods of primary schools are still used, and the study habits of preview, review, summary and self-adjustment have not yet been developed, which is obviously not conducive to the formation of good learning methods and the improvement of learning quality.

Finally, I think the first teacher in learning is interest. Some people think that children's interest in learning should be cultivated first. In fact, I think that as long as children can master the correct learning methods, learning is a relaxing and enjoyable thing, and they will naturally be interested, so we still have to do the first three tasks well, which is the most important thing.
