1. Overall goal: through the two-week final review, sort out the knowledge system that students have learned this semester, retrieve the knowledge that students have forgotten, and form a complete knowledge system. Strive to make progress in the final exam, and draw a satisfactory full stop for this semester's work. Second, review content and objectives: The contents of this semester's textbooks include: simple statistics, cuboids and cubes, factors and multiples, the meaning and nature of fractions, addition and subtraction of fractions, and graphic transformation. The review goal of Simple Statistics is to make students further master the method of data arrangement, make simple statistical tables and calculate the average, median and mode according to statistical data. The purpose of reviewing cuboids and cubes is to help students deepen their understanding of their surface areas and volumes, further master their calculation methods, improve their ability to solve practical problems and cultivate the concept of space. The purpose of reviewing "Factor and Multiplication": 1. Let students master the related concepts of factor and multiple systematically, and further clarify the relationship and difference between concepts. 2. Master the method of decomposing prime factors and the method of finding the greatest common factor and the least common multiple. The review goal of "the meaning and nature of fractions" is to enable students to further master the meaning, nature, significance and methods of fractions and general fractions. The review goal of Addition and Subtraction of Fractions is: 1. Make students further master the meaning of score addition and subtraction and various calculation rules, and be proficient in the calculation of score addition and subtraction. 2. Further master the operation sequence of decimal addition and subtraction mixed operation and decimal addition and subtraction mixed operation, and be proficient in addition and subtraction mixed operation. 3. Further use the commutative law and associative law of addition to simply calculate the addition and subtraction of fractions. The review goal of "Graphic Transformation" is to let students further understand the characteristics and properties of graphic axisymmetry and axisymmetry, draw an axisymmetrical graphic with a fixed number of rotations of a graphic and a simple graphic, and develop the concept of space. Third, review measures: 1. Excellent students are better: for outstanding students such as Zhang Yu, Li, and Li, it is necessary to make clear the mastery level of application problems: master the method of solving simple application problems with column equations, understand the solution of fractional application problems, and understand the unit "1". Good students practice this kind of questions more and strive for better grades. 2. Li Yong, Hang Yujie, Li Yulian, Li Chaoqun and Xu Wenhao. These middle school students practice basic problems more, so as to master formulas, definitions and applications skillfully. Appropriately contact and expand thinking, and prepare for solving the expansion problem. 3. Pay attention to underachievers and strive to "protect the middle and catch both ends". It is very important to do a good job of underachievers in the class. There are many underachievers in this grade, such as how to be happy, He, He, Zhao Jiajia and other students with poor foundation. Pay close attention to calculation problems, basic application problems and some definition problems. 4. Review the teaching mode and problems of the final review of textbooks. Four. Arrangement of review time and content 6.3-6.5 Review factors and multiples 6.6-6.8 Review cuboids and cuboids 6.9-6. 10 Review the significance and nature of scores 6. 1 1-6. 15 Review the transformation of graphics. 6. 16 to 6. 17 Comprehensive review of Mathematics Wide Angle. According to the contents of this book and students' knowledge, prepare some comprehensive exercises for students to comprehensively test their mastery and meet the exam.
