This textbook is the last textbook in the first period. Through general review, students can gain more solid knowledge, improve their computing ability, develop their sense of numbers, spatial concepts and application awareness, solve simple practical problems with their learned mathematics knowledge, gain successful learning experience, increase their interest in learning mathematics, establish confidence in learning mathematics well, and fully realize the teaching objectives of this textbook and the first learning period.
1. Consolidate what students have learned and further improve their basic knowledge and skills through general review.
2. Through induction, arrangement and practice, improve and develop students' computing ability, sense of number, spatial concept, statistical thinking and application consciousness.
3. Enable students to solve simple practical problems with what they have learned, gain successful learning experience and improve their interest in learning mathematics.
Second, the analysis of class students:
A comprehensive analysis of the actual situation of junior three students at the end of the term shows that students' learning mentality is not stable, and there are many mistakes in their eagerness to achieve success, mainly reflected in the multiplication of numbers and double digits in algebra. Students use the draft book improperly, and hasty calculation is prone to errors. Some students will confuse multiplication with addition. This problem makes it easy for students to make mistakes when calculating numbers involving thousands of totals in the average. In solving problems (application problems), some students often write them down in a hurry without reading and understanding the problems, which leads to mistakes, especially in flexible regional problems. It is worth noting that the phenomenon of polarization has gradually emerged this semester. Excellent students can learn new knowledge easily, use it freely and have good study habits. Secondary school students have solid knowledge and can study independently, but their thinking is not flexible enough and they lack problem consciousness. Underachievers are slow to accept knowledge, not good at thinking and solving problems independently, and their academic performance is unstable and steep. Therefore, we should pay attention to both ends when reviewing, not only to make up the difference, but also to cultivate Excellence.
Third, review the difficulties and key points
(1) review points:
About decimal addition and subtraction, multiplication, statistical knowledge, area and solving simple practical problems.
(2) review difficulties:
Can use the knowledge learned to correctly analyze and solve simple practical problems, and strengthen the cultivation of statistical concepts and spatial concepts.
(3) Review key points:
Inspire and guide students to learn to analyze and think in independent thinking and cooperative communication. Improve the ability to solve problems.
Fourth, review content:
(a) Numbers and algebra
A preliminary understanding of 1, decimal and fractional, addition and subtraction operations.
3. Multiplication of two digits and two digits; Division and mixing operation of one digit with two digits or three digits.
(b) space and graphics
1, get a preliminary understanding of simple graphics and its basic characteristics.
2. Understanding the perimeter of graphics and calculating the perimeter of rectangles and squares.
3. To understand the meaning of area, you can use optional graphic units to estimate and measure the graphic area, understand the necessity of unifying the area units, know and understand the area units, and carry out simple area conversion; By exploring and mastering the area formulas of rectangles and squares, we can estimate the area of a given rectangle and square.
(3) Statistics and probability
Statistics and possibility, through rich examples, understand the meaning of average, realize the necessity of learning average, find the average of simple data, answer simple questions according to the data in statistical charts, and communicate with peers; Be able to list all possible results of simple tests; Know the possibility of an event; Describe the possibility of some simple events and communicate with peers.
(4) Practical activities
Apply what you have learned to analyze and solve problems with examples in life, and form certain problem-solving strategies.
Five, review points:
Teacher:
1, according to the learning situation of each class, make a review plan, prepare and do a good job in each review class.
2. Use various means to stimulate students' interest in learning, improve the teaching effect, pay attention to the integration, coherence and systematicness of knowledge, and guide students to sort out what they have learned.
3. While mastering the basic knowledge, comprehensively cultivate students' mathematical literacy, cultivate students' attitudes and habits of summing up and reflecting, and improve students' learning ability.
4. The design of review homework is hierarchical, comprehensive, interesting and open, and it is necessary to correct it in time, find problems in time, fill in gaps and clean up knowledge every day.
5. Pay attention to the work of cultivating excellent students, pay attention to students' learning emotions and attitudes, and strengthen communication with parents.
(2) Students:
1, ask for active learning in attitude, pay attention to review, dare to ask questions, and ask if you don't understand.
2. Listen attentively in class, think positively about speaking, and learn to listen to others' speeches.
3. It is required to finish homework on time and seriously after class, and conduct self-reflection in time.
(3) Measures to improve and make up for differences:
1. Pay attention to learning and understanding the knowledge of numbers and counting from students' existing knowledge and life experience.
2. Students should take the initiative to review. Lay a solid foundation of knowledge and skills. At the same time, we should attach importance to the cultivation of students' innovative spirit.
3, grasp the teaching requirements, not too high, so that students can improve on the original basis. Select exercises carefully, not engage in the sea of questions.
4. Improve the evaluation of students. If they make mistakes, they can be rewarded, prompting students to check and analyze their mistakes and make continuous improvement.
5. Make up lessons after class, and take the form of "one-on-one" to mobilize students to help them make progress together, and at the same time get the cooperation of parents to encourage and supervise their progress.
6. Actively coach poor students, always pay attention to these students, and ask more questions in class, give more guidance on homework, practice more explanations, praise more, encourage more, and provide more opportunities for performance. Give some thoughtful questions to satisfy the students who study better.
Sixth, review specific measures:
Understand and analyze the basic situation of students mastering each part of this lesson comprehensively. Then, according to the actual situation, make a feasible review plan comprehensively.
1, calculation part:
A. oral calculation: adhere to regular practice and arrange 3 minutes for each class. Practice in as many ways as possible, such as attending classes and counting, to see who is doing it right and fast, so that students can use it in the calculation process.
B. Calculation by multiplication and division: First, review the calculation rules and precautions, and focus on learning the calculation strategies and methods between two digits and three digits.
2. Problem-solving part: Focus on guiding students to analyze the quantitative relationship in the stem, and compare the stem with similar structure, so that students can see the conditions of the stem. When the problem changes, how do the steps to solve it change accordingly?
3. Geometry of figures: guide students to summarize and sort out, and help students distinguish the differences and connections between these figures.
4. Unit of measurement: Combine with real life to deepen students' understanding and application of them.
5. Pay attention to the transformation of students with learning difficulties. In class, we should pay more attention, communicate with parents, change their learning attitude to the maximum extent, and strive for progress for these students with the help of the pressure of final exams.
6. Pay attention to adjust the review plan in time according to the problems in the review process.
