Geogebra has some pretty awesome online tools. These task cards are perfect for some easy and quick practice. The first 9 cards review the names of the three-dimensional figures and the other 18 cards review identifying the shape that results from a 3-D slice. This set of task cards includes 27 cards. You can do so many different activities like Scoot, partner work, whole class with whiteboards, or exit tickets. Overall, this game gets students some practice of visualizing 3D shapes on paper and thinking about what the cross sections look like. Students play in partners and end up talking a lot about the shapes they’re examining and their cross sections. I especially love the real world examples. Also, it works really well for a fast finisher partner activity. You can use this activity as an anticipatory set. Three of the cards have just plain old shapes and the last one has real objects. It includes four different tic tac toe cards. People really seem to like this tic tac toe game. You’ll see that this list of activities offers a wide range of practice. There’s a lot of hands-on things for students to do, and they really get into these activities. In this post I’d like to share some of these ideas with you. In my class we do a lot of practice with both paper and online games and activities. That’s something that makes this topic unique. One thing that I find interesting about teaching this topic is that it’s about three dimensions, but students have to understand it in a two dimensional space on paper or computer screens. But there’s other ways to help students see and understand this topic, so I’m sharing 12 other activities today (but you can see some different versions of this play-doh activity here and here). Students make the 3-D shapes out of play-doh and then cut them with a string of some sort. When you look for ideas for teaching this topic, you’ll inevitably find an introductory activity using play-doh. Finding the shape that results from cutting a three-dimensional shape is a fun topic.
