Teachers, save “Math 9.1 Geometric Nets 几何网” to assign it to your class.

Today we are going to have some fun building geometric nets. A geometric net is a flat face. All 2D shapes make up the faces of 3D shapes. I am providing you a list of materials you could use for this activity in case you need different ideas. I can send you a printable version of the 3D nets that we will be building today if you need the file. We will use the shapes we make today later this week in our lessons. Watch this to give you an idea and let's get started!!! A play dough has been attached as an optional activity if you need to make some play dough to complete this activity. There is NO need to send your teacher a response to this activity. We will be able to tell if you created your nets as the next couple of lesson will make use of these shapes you are building. 今天，我们要做一些有趣的几何网。几何网是个平面，所有的二维图形都可以构成三维图形的面。如果你需要不同的想法，我会给你提供一份可用于此活动的材料清单。如果你需要文件，我可以给你发一个可打印版本的三维图形网络，我们今天将开始构建这个几何网。在本周接下来的课程中，我们会使用今天制作的形状。请观看这个视频，它可以给你一些启发。 让我们开始行动吧！此活动不需要你给老师回复。如果你做了几何网，在接下来的几节课中就可以使用你今天制作的这些形状。
