这两个星期，我们数学一直在学习第二单元20以内的退位减法。同学的计算速

For the past two weeks, we have been learning abdication and subtraction within 20 of the second unit of mathematics. The calculation speed of the students has also improved compared with the beginning of the semester, but there is still a lot of room for improvement. Next, we will strengthen the practice of calculation to lay a solid foundation for addition and subtraction within 100 in the future. In addition to computing, we also learned the problem of more than less. One number is more than the other, one number is less than the other, and the difference between the two numbers is calculated by subtraction, and the larger number reduces the number. The students have been studying very seriously, and I hope to continue!

For the past two weeks, we have been learning the abdication subtraction within unit 2 20 in mathematics. The calculation speed of students has also improved compared with that at the beginning of school, but there is still a lot of room for progress. Next, we will strengthen the calculation practice to lay a solid foundation for the addition and subtraction method within 100 in the future. In addition to calculation, we also learned the problem of more than less. One number is more than the other, and one number is less than the other. The difference between the two numbers is calculated by subtraction, and the large number is reduced by decimals. The students are studying very seriously and hope to continue!

For the past two weeks, we have been studying the abdication subtraction in Unit 2 20 in mathematics. Students' calculation speed has also improved compared with that at the beginning of school, but there is still much room for improvement. Next, we will strengthen the calculation practice to lay a solid foundation for addition and subtraction within 100. In addition to calculation, we also learned fewer problems than Dobby. One number is more than the other number, one number is less than the other number, and the difference between the two numbers is calculated by subtraction, and the large number decreases the number. Students are studying hard, and hope to keep it up!
