How many versions of primary school mathematics are there? Which is the most widely used?
Comparison between Qingdao Edition and People's Education Edition. Specific capacity. Judging from the quantity of content, the capacity of the People's Education Edition is smaller than that of the Qingdao Edition. Compared with Qingdao edition, People's Education Edition has more knowledge of identifying clocks and watches, but less knowledge of identifying positions, statistics and comparison. The calculation part of the People's Education Edition is arranged to carry addition within 20, and there is no abdication subtraction. The Qingdao Edition has abdication subtraction within 20 in Unit 7.

Not an arrangement. The content arrangement of the first volume of the first grade mathematics in People's Education Edition is less jumping and less difficult than that in Qingdao Edition. For example, the People's Education Edition arranges the understanding and addition and subtraction of 1~5 in the third unit, the understanding and addition and subtraction of 6~ 10 in the sixth unit, and the Qingdao Edition directly arranges the addition and subtraction of numbers within 10 in the third unit.

Illustration of life situation. The illustrations of life situations in the first volume of Mathematics Grade One published by People's Education Edition are based on students' existing lives and are more suitable for rural children in rural schools. The situation map in the first volume of Grade One Mathematics in Qingdao Edition is based on students' existing life experience, which is more suitable for children with urban life experience.

Not practical activities. People's Education Edition has arranged two practical activities for the first year of mathematics, namely, Mathematics Paradise and our campus. The practical activities of the first volume of the first grade of mathematics in Qingdao Edition were also arranged twice, which were to find out the number around and how many cloves of garlic there were.

Instead of showing it. The contents of the first volume of the first grade mathematics published by People's Education Press are presented directly, leaving less room for students to think. The content of the first volume of the first grade mathematics in Qingdao Edition is indirectly presented, leaving students more room for thinking.

Through the comparison of the above five aspects, I think that the starting point of the first-grade mathematics volume of the People's Education Edition is relatively low, the difficulty is relatively small, and the challenge is less, which is more suitable for children in rural primary schools with weak preschool education; The first volume of the first grade mathematics in Qingdao edition has a high starting point, great difficulty and challenge, and is suitable for urban schools with solid pre-school education. Because of the great gradient of the textbook in Qingdao edition, it is necessary for our teachers to put kung fu ahead and have an overall grasp of the textbook before teaching. Second, the style arrangement and writing intention of the textbook. The content of each textbook is arranged according to four major fields, and each unit is provided with information window, cooperative inquiry and independent practice. Did I learn? Harvest gardens are in the same column,

1, "Information Window" (thematic situation map)-Beautiful scenery of Qingdao edition primary school mathematics textbook II. Cooperative inquiry (Senior one: you talk about me; The second grade is: you ask me)-the navigation column names of teaching methods and learning methods carry out the concept of curriculum reform, and the presentation form of inquiry links also leads to new learning methods. 3. Problem Pocket-Store valuable math problems 4. Expand the platform (also known as related links)-different landscapes of textbook interpretation 5. Self-practice-the expansion, application and deepening of examples. 6. Smart house-implement the concept that "different people get different development in mathematics". 7. Do you know? (also known as information through train)-expanding mathematical culture
