Teachers, save “Math 7.3 3-D Shape Vocabulary 三维…” to assign it to your class.

Yesterday, we learned more about 2-D shapes. Today we are going to look closer at 3-D shapes and learn about their attributes. This will build up your spatial sense and reasoning for the activities that are coming next week. Today’s activities do not require you to respond to the questions prompting further thinking. You only have to watch and listen to the conversation Ms. Kennedy has with Bookworm and think about 2-D and 3-D shapes in your own home. On Friday, we will have a tech-free day. Let's see what Bookworm build's on Friday. 昨天我们了解了更多关于二维图形的信息，今天我们将更深入地研究三维图形并了解它们的属性。这将增强你对下周活动的空间感并提升推理能力。今天的活动不需要你回答那些要进一步思考的问题，你只需观看和认真听Ms. Kennedy与Bookworm的对话，并思考自己家里的二维和三维图形。星期五将会是无科技的一天，让我们看看星期五Bookworm会做什么。
