Free 3D Shape Activity: Mystery Bags

February 25, 2019

I love teaching all about 2D and 3D shapes in the classroom. It is a unit of study that my first graders always seemed to just “get.” It was tactile and to the point.

 I am always on the hunt for fun and new shape activities, so I thought I would share one of my favorite 3D shape activities: Mystery Bags! I should note that this type of activity is one I would use after I’ve already taught the attributes of each 3D shape.


You can see how to play below and while you’re watching the video, you can also grab the FREE recording sheet so you can play in your classroom right away. Be sure to subscribe to my channel and click the bell so you are notified of all my new videos!
