For our second lesson, I gave each group a set of 3d shapes. They were then given 5 minutes to build anything they wanted while working together. (The teamwork was amazing.) After that, I called out different shapes and they composed new ones using the shapes I called out.
It was amazing what they created! The thing I enjoyed even more was hearing them tell me about the shapes and their attributes afterwards. One little girl even looked at me and went "That was our math? Thank you!"
I love it when they are really excited about our lesson and don't realize they're learning!
