We just finished learning about 3D shapes and I wanted a way for the kiddos to review their learning during their independent math time.  I came up with this idea while cruising through the Lego store with the hubs.  I filled a small box with a variety of legos and I had the kids open up the Lego Geometry assignment in Google Classroom.  The kiddos were asked to build a cube and a rectangular prism.  I debated about dictating the size, but decided to let them free build and I am glad I did.  Once the students finished building they filled out their slides in Google classroom.  I plan to print them out into a geometry book.  You can see an example of the slides below.  If you want a copy of the slides for use in your classroom, just click on the photos below.
