一年级学生这星期开始我们学习立体图形，主要有长方体，正方体，圆柱，球。

For the first-year students, we will learn three-dimensional graphics this week. There are mainly cuboid, cube, cylinder, and sphere. They will recognize, speak, and tell the characteristics of these three-dimensional graphics. <br>For the second-year students, we continue to learn two-digit continuous addition and subtraction, and the mixed operation of addition and subtraction. From next week, we will learn the understanding of the third unit corner. They need to recognize acute, right and obtuse angles. And can count the total number of angles.

First-year students this week began our study of stereoscopic graphics, mainly box, square body, cylinder, ball. They'll recognize, they'll say, and they'll be able to tell the characteristics of these stereoscopic graphics.<br>Second-year students continue to learn double-digit consecutive subtracts, plus and minus mixed operations. Starting next week we'll be learning about the third module corner. They need to know sharp angles, right angles, blunt angles. And can count a total of several corners.
