First of all, often review the teaching objectives:
1, systematically organize knowledge. Practice shows that students' mastery of mathematics knowledge depends to a great extent on the systematic arrangement in review, and the review after graduation from primary school forms a network structure for what they have learned in primary school.
2. Comprehensively consolidate the knowledge learned. Graduation review itself is a process of re-learning, that is, mastering knowledge from the level of mastery to the level of proficiency.
3. Check for leaks. In combination with reality, there are inevitably some problems in students' understanding and mastery of knowledge. Therefore, the re-learning process of graduation review should make up for the defects in knowledge mastery.
4. further improve the ability. Further improve students' ability of calculation, initial logical thinking, spatial concept and solving practical problems. Let students fully reflect the change from "learning" to "learning" in review.
Second, the main content of the general evaluation:
1. Make students master the basic knowledge about integers, decimals, fractions, ratios, simple equations and so on systematically and firmly. , have the ability to perform four operations on integers, decimals and fractions, use the simple algorithms learned, calculate reasonably and flexibly, solve simple equations, and develop the habit of checking points.
2. Make students consolidate the appearance of the size of some units of measurement they have learned, firmly grasp the progress between the units they have learned, and rewrite the names simply and skillfully.
3. Make students firmly grasp the characteristics of the geometric shapes they have learned, and be able to skillfully calculate the perimeter, area and volume of some geometric shapes, thus consolidating the simple drawing and measuring skills they have learned.
4. Make students master the preliminary knowledge of statistics, read and draw simple statistical charts, and calculate the average problem.
5. Make students firmly grasp some common quantitative relations and solutions to application problems, and be able to flexibly use what they have learned to independently answer uncomplicated application problems and some simple practical problems in life.
Three. General review arrangement
(a) number and number operation,
1. Systematically sort out the contents of numbers, establish a concept system, and strengthen the understanding of concepts, including the meaning of numbers, reading and writing of numbers, rewriting of numbers, comparison of numbers, divisibility of numbers and other knowledge points.
2. Communicate the connection between the contents and promote the overall perception, including "the nature of fractions and decimals" and "the conceptual comparison of divisibility".
3. Fully define four operations and calculation methods, and improve the calculation level, including "the meaning and law of four operations" and "elementary arithmetic".
4. Use algorithms to master simple operations and improve calculation efficiency, including "algorithms and simple operations".
5. Carefully design exercises to improve comprehensive calculation ability.
