Compared with the old version, the main change of the new version of mathematics textbooks for grades three to six is that the overall difficulty is reduced according to the requirements of the new curriculum standard, especially the difficulty in probability and statistical content has been greatly adjusted. The contents of median and mode in the first volume of Probability Calculation and Statistics in grade five have been deleted, and probability calculation is no longer studied in primary schools.
In addition, the new edition of primary school mathematics textbooks pays more attention to students' ability to solve practical problems by using mathematics. For example, the "decimal multiplication" unit in the first volume of the fifth grade added a practical question of "how much does it cost to take a taxi?" For example, "The starting price of 3 kilometers is 7 yuan, and the part exceeding 3 kilometers is per kilometer 1.5 yuan." Life examples like this should be applied to decimal multiplication calculation.
However, after the textbooks for grades three to six are updated this fall, there will be overlapping teaching contents. For example, the content of "hectares and square kilometers" in the textbook of grade four students has actually been learned in the old textbook of grade three. A sixth-grade primary school teacher said that she would take sixth-grade students at the beginning of school. Seeing the new textbooks is a bit hectic, and the old and new textbooks need to be compared one by one. But on the whole, the adjusted textbooks are more in line with the teaching rules and the knowledge points are more reasonable.
