一年级数学现在开始在学习平面图形，我们这星期学习了正方形，长方形，三角

The first grade mathematics is now starting to study plane graphics. We have studied squares, rectangles, triangles, circles, and parallelograms this week. I remember when I was teaching three-dimensional graphics last semester, you taught them flat graphics. If they forget, you can teach them again, as a review. Of course, you can also teach them three-dimensional figures, such as: cube, cuboid, cylinder, circle.

First-year math is now learning flat graphics, and this week we've learned squares, rectangles, triangles, circles, parallelographs. I remember when I was teaching stereoscopic graphics last semester, you taught them flat graphics. If they forget, you can teach them again and use it as a review. Of course you can also teach them three-dimensional graphics, such as: square, box, cylinder, circle.
