这两个星期我们数学学完了第三单元分类与整理的内容，还学习了第四单元10

In the past two weeks, we have completed the classification and sorting of the third unit of mathematics, and also learned the understanding of the number within 100 of the fourth unit. The students have already been able to count from 0 to 100 one by one, two by two, five Each of five counts, and 10 of 10 counts. Also learn the composition, reading and writing of numbers up to 100. In addition to this content, we are continuing to strengthen the calculation of abdication and subtraction within 20, requiring students to be fast and correct. The increase in calculation speed will help children reduce the time for homework and lay a solid foundation for subsequent addition and subtraction within 100. Base. When the fourth unit is over, we will conduct a mid-term exercise to test students' mastery of mathematical knowledge points.

In the past two weeks, we have finished the classification and arrangement of unit 3 in mathematics, and also learned the understanding of numbers within 100 in unit 4. The students have learned from 0 to 100, one by one, two by two, five by five, 10 by 10. Also learned the composition of numbers within 100, reading and writing numbers. In addition to this content, we continue to strengthen the calculation of abdication subtraction within 20, and require students to be fast and correct. The improvement of calculation speed is conducive to reducing the time for children to do homework and laying a solid foundation for the subsequent addition and subtraction within 100. By the end of unit 4, we will have a middle and primary school exercise to test the students' mastery of mathematical knowledge.

In the past two weeks, we have learned the content of the classification and arrangement of Unit 3 in mathematics, and also learned the knowledge of the numbers within 100 in Unit 4. The students have learned from 0 to 100 one by one, two by two, five by five, and ten by ten. I also learned the composition, reading and writing of numbers within 100. In addition to this content, we are continuing to strengthen the calculation of abdication subtraction within 20 minutes, requiring students to be quick and correct. The improvement of calculation speed will help children to reduce their homework time and lay a solid foundation for the subsequent addition and subtraction within 100 minutes. By the end of Unit 4, we will have a period of primary and secondary exercises to test students' mastery of mathematical knowledge points.
