Suggestion 1: Three things should be made clear in class: one is to make it clear slowly over and over again, the other is to make it clear step by step, and the third is to make it clear during students' golden study. Remember: it is better to talk about a problem of primary school students several times. Imagine that the students who speak for the second time are talking loudly and will not affect their classmates. In addition, when the teacher speaks the second and third times, the speech speed is getting faster and faster, and the students with learning difficulties still can't understand it slowly, and they can't understand it quickly.

Suggestion 2: the teacher should speak slowly, remind students of the key points with hints and tone, and pay attention to the class; Let the students repeat, repeat and talk to each other until they recite the key contents; Leave enough time to think when asking questions, that is, there is a waiting time. Remember: will primary school students be the focus of the three-to five-minute lecture?

Suggestion 3: Teachers should have seed classroom awareness and knowledge group concept, find the core knowledge of the joints and attachment points of students' brain knowledge, make key breakthroughs, and make natural knowledge learning get twice the result with half the effort.

Recommendation 4: The types of math application questions in the next paragraph are: pure picture, schematic diagram, picture+text, and pure text. Consciously carry out the conversion among written language, graphic language and symbolic (formula) language to realize the multi-representation and meaningful construction of knowledge. That is, text questions let students convert into graphics; Graphics are converted into words, mathematical formulas are converted into words and so on.

Suggestion 5: Let students understand the meaning of addition and subtraction and train them to create application problems. (1) question training: for example, 18-5=? What's the difference between 18 and 5? What's the difference between 18 and 5? What's the difference between 18 and 5? What's the difference between 18 and 5? What's the difference between 18 and 5? What's the difference between 18 and 5? Integer 18 minus 5. Wait, you can also ask, how many formulas can you write based on this formula?

(2) According to the formula of 18-5, create an application problem in three real life scenarios?

(3) Change creative application problems into two-step and three-step application problems?

Suggestion 6: When solving practical problems (application problems), consciously infiltrate and construct the ability to read, examine and ask questions: What are the conditions of this problem? What is the conclusion? What is the relationship between conditions and conclusions? (that is, pay attention to math reading).

Suggestion 7: Consciously cultivate the ability of inductive thinking, deductive thinking, divergent thinking and epiphany thinking. That is, a knowledge point should be trained from positive, negative, variable and comprehensive angles.

Suggestion 8: Students should be consciously infiltrated in the classroom to cultivate their ability to summarize and express mathematical concepts, laws, reasoning and the results of their own thinking process in language. That is, to cultivate primary school students' ability to speak and summarize systematically and to express their thinking process and results.

Suggestion 9: Let students express true and false questions and multiple-choice questions with gestures. For example, the four answers to multiple-choice questions can be represented by 1, 2, 3 and 4 fingers respectively, and the question of right or wrong can be represented by the gesture V×××.

Suggestion 10: Try to let students not use erasers and cultivate concentration and carefulness. Wrong questions are not allowed to be erased with rubber, but traces are left and the certificate is put aside. After booking the certificate, the teacher will ask one or two similar questions to consolidate it.

Suggestion 1 1: strengthen the examination of homework papers: covering the answers and counting them again is the best examination method in the next section; Do you want to check the missing questions and questions? Have you seen the demand clearly? Is the unit unified and replaced by the unit? Application questions focus on checking whether the sub-column of the formula is correct. Set, answer, etc.

Suggestion 12: Let the students with learning difficulties tell their peers the wrong questions twice. Imagine, it can be said clearly that he really will.

Suggestion 13: Set the lottery operation. In order to stimulate students' enthusiasm for learning, two mysterious boxes can be placed in the eye-catching position of the classroom. Teachers can selectively put some improvement questions and Olympic Games questions in the box in front of students. At the same time, it is required that only students who have completed their homework or who have performed well in class are qualified to draw a question in the first box and ensure that other students can't see it. If it is self-study, you can draw questions again, otherwise you will be automatically disqualified from drawing lots. If you break through the three levels in a row, you will be qualified to extract questions in the second box ... Through this form of packaging, the teacher makes the students turn problem-solving into a pleasure, and the students' internal drive begins to play a role. At this time, students' learning is not forced by the teacher, but from the heart, "I want to learn."

Suggestion 14: three-dimensional evaluation of primary school students' homework, one evaluation of writing, two evaluation accuracy rates and three evaluation methods.
