The final term is coming. In order to organize review better and more effectively, and let students master the learning content of this semester more systematically,

This review plan is specially formulated.

First, review purpose

1, so that students can further understand and master the knowledge they have learned and make it more systematic and perfect.

2, enable students to further consolidate and improve their knowledge, and can apply what they have learned to solve some practical problems.

3. Make students lay a good foundation in mathematics, improve their learning ability, cultivate their study habits, and prepare for the connection between primary and secondary schools.

Second, review principles

1, fully mobilize the enthusiasm of students for autonomous learning, encourage students to consciously organize review and improve their review ability.

2, fully reflect the guiding role of teachers, the key and difficult points of knowledge points should be explained in time to ensure the review effect.

3. Fully embody the educational principle of teaching students in accordance with their aptitude, and design different teaching contents and methods for students at different levels.

Learning methods, checking for missing parts, focusing on answering questions, and improving the review effect.

Third, review methods (number and algebra, space and graphics, probability and statistics)

1, lead students to organize review according to units, and consolidate basic knowledge.

Teachers should grasp the important and difficult points of knowledge in units, integrate and link relevant knowledge, and form a complete knowledge network. For example, the review of application problems can link from simple fractional application problems to slightly complex compound application problems, integrate and link knowledge, further understand the relationship between quantity and quantity, and improve the ability to analyze and solve application problems.

2. Strengthen the training of computing ability.

In the usual teaching, it is found that students' computing ability is generally low, especially in Class 6 (2), so we should strengthen the training of computing ability in review. The training of students' computing ability is not only a mechanical repetitive exercise, but also to let students master the correct computing methods and strategies. Let the students remember "look at two, think about three calculations" and see the numbers and symbols in the questions clearly; Think about the order of calculation, where to calculate orally, where to calculate manually and where to calculate simply; Finally, write the calculation.

3. Strengthen the connection with reality.

Adapt to the spirit of the new curriculum standard, strengthen the comprehensive application of knowledge and contact with life, and improve students' ability to solve practical problems.

4. Combining lectures with practice

Talk and practice, find problems in practice.

5, hierarchical guidance

According to the specific situation of students, targeted review, put forward different requirements for poor students and excellent students, examine questions at different levels and guide them at different levels.

Fourth, specific arrangements.

1, decimal multiplication, division and its elementary arithmetic

2. Slightly complicated fractional application questions

3, percentage and application questions

4, the circumference and area of the circle

The second stage: comprehensive practice, combination of lecture and practice (special training at the end of the term)

Give students some comprehensive papers, find problems through practice and give timely guidance.

The third stage: layer-by-layer audit, checking for leaks and filling gaps.

Give special guidance and guidance to underachievers, and check for leaks and fill vacancies. Do more exercises for top students to improve their analysis and answering ability.

The significance of percentage and the review of the application of tax and interest percentage

Review purpose: 1. Through review, students can further understand the meaning of percentage, master the characteristics of tax and interest percentage application questions, and be skilled in answering such application questions. 2. Improve students' problem-solving ability.

Review key points: the meaning and application of percentage.

Review difficulty: the application of percentage.

Teaching process:

First, guide students to review and form a knowledge network

Percentage of relevant knowledge

The meaning of (1) percentage means that one number is a percentage of another. Percentages are also called percentages or percentages. Writing: 90% 108.5%

What's the difference between percentage and score? Let the students make it clear that the score can represent both a number and the ratio of two numbers; Percent only indicates the ratio of two numbers, and you can't write the unit name.

(2) Application of taxes and interest.

How to get interest? Interest: interest = principal × interest rate × years.

Second, consolidate the practice.

1, students give examples of sentences containing percentage and tell the meaning of percentage.

The sales of a paper mill in April is 30 million yuan. If the consumption tax is paid according to the sales, how much will it cost in April?

The turnover of a hotel in June 5438+ 10 is 500,000 yuan. If the business tax is paid according to the turnover, how much business tax should be paid in 5438+ 10?

According to the individual income tax law, the balance of performance income after deducting 800 yuan is subject to individual income tax at the rate of 20%. What is Wang Hua's after-tax income after this performance?

6. The annual interest rate of one-year fixed deposit is: after one year, the deposit of 10000 yuan is subject to interest tax. How much interest tax should I pay?

How much interest tax does Li Yan have to pay to withdraw money after three years?

8. Shuang Lee deposited 500 yuan given by his grandfather in the bank for two years, with an annual interest rate of%. After two years, Shuang Lee had to pay interest tax when depositing. How much money should Li Shuang get back after the expiration?

9. Uncle Li has deposited 654.38 million yuan in the bank this year, with an annual interest rate of three years, which will expire after three years. After deducting the interest tax, can he buy a 6000 yuan color TV?

Review of percentage application problems

Purpose of review:

1, so that students can master the application problems such as "What is the score (percentage) of a number" and "What is the score (percentage) of a known number".

2. Improve students' ability to analyze and solve practical problems and cultivate students' dialectical thinking of "unity of opposites".

Review key points: finding the corresponding relationship between quantity and rate is the key point of teaching; It is difficult to draw line segments of complex application problems in teaching.

Teaching process:

First, introduce a conversation

We reviewed three kinds of application problems, that is, what is the score (percentage) of a number, what is the score (percentage) of a number and what is the score (percentage) of a number. In this lesson, on the basis of the first two lessons, we will continue to review the application problems of fractions and percentages. (blackboard writing: review of scores and percentages)
