这两个星期数学学完第二单元的内容万以内的加法和减法（一），我们学会了整

In these two weeks, after finishing the second unit of mathematics, adding and subtracting within ten thousand (1), we learned how to add and subtract three-digit numbers to three-digit numbers through simple calculations, and also learned how to calculate through calculations. , Quickly solve practical problems in life. The students are studying very hard and hope to continue. Starting next week, we will continue to study the content of the third unit-measurement.

In these two weeks of mathematics, we learned to add and subtract less than ten thousand units of content (i), we learned the whole ten three-digit plus minus three-digit simple calculation by swinging vertical, but also learned through estimation, quickly solve the real problems in life. Students are studying very seriously, I hope to continue to maintain. Starting next week, we will continue to study module 3 of --- measurements.

In the past two weeks, we have learned how to add and subtract three digits by pendulum, and how to quickly solve practical problems in life by estimating. The students are studying very seriously and hope to keep on learning. Starting next week, we will continue to study unit 3, measurement.
