In geometry we are doing a Brain Drain. A Brain Drain is when you take everything that you know about a topic and write it down on a piece of paper. The main purpose for a Brain Drain is so people can know what you know about a subject. It also lets your teacher know what you already know and what you still need to learn.
This is also for you to know how much the other person knows about a subject. First, when we started a Brain Drain we discussed what we knew about geometry with our group. Next, we wrote what we said on the sticky note.When we were writing what we knew about geometry on a sticky note, most of us wrote about angles, shapes, polygons, volume, 2D, and 3D shapes. After that, our class discussed what we wrote on our sticky note. Some people wrote on more than one sticky note. Lastly, we stuck our sticky notes on the big green piece of paper and hung it outside to share our knowledge with everyone.
This is a great learning activity because we got to share what we knew and we got to teach our classmates.
