The sixth grade Jiangsu Education Edition mathematics supplementary answer: The sixth grade first volume mathematics curriculum outline comes from the user: RayChuKeh.
Course Name: Mathematics Course Type: Compulsory Course of Elementary Mathematics
Source: PEP compulsory education curriculum standard textbook "The first volume of sixth grade mathematics" Applicable grade: the sixth grade of primary school.
Teaching time: about 60 class hours. Teaching target: sixth grade students. Designer: Zhuge Leirui.
Course background This semester, the course is rich in content, paying more attention to students' experience and understanding, reflecting the formation process of knowledge, encouraging the diversification of algorithms, and then changing students' learning methods and reflecting teaching methods, so that students can learn mathematics in a pleasant environment and feel the value of mathematics. Specific performance: In number and algebra, this textbook arranges fractional multiplication, fractional division, ratio and percentage. The teaching of fractional multiplication and division is based on the previous study of integer and decimal calculation, focusing on cultivating students' ability to calculate four fractions and solve practical problems related to fractions. The calculation ability of four fractions is an important basic skill for students to further study mathematics, which students should master. Preliminary knowledge is taught on the basis of learning division, fraction and other knowledge, which is more widely used than in life, and is also the basis of learning pi, percentage and proportion in the later stage. Percentage is widely used in real life. Understanding the meaning of percentage and mastering the calculation method of percentage will solve simple practical problems about percentage, and it is also the basic mathematical ability that primary school students should have. In terms of graphics and geometry, this textbook arranges two units: position and direction and circle. On the basis of existing knowledge and experience, the teaching of position makes the formation process of academic knowledge understand and learn to express position with distance and direction through rich mathematical practice activities; By drawing curves—
