I absolutely love the blog “Growing a STEM Classroom” by Smart Chick! She is the STEM coordinator for her K-5 building, and with 20+ years of teaching, she knows her stuff! Our school purchased her STEM challenge packs from Teachers Pay Teachers last year, and a number of teachers have enjoyed the easy implementation.
There is one particular challenge that I think works especially well with Back to School Team-Building goals. It is the “Cup Pyramid: Engineering Challenge”.
Here is the description from TpT.
I used this with my sixth grade students at the end of the year during one of our Olweus classroom meeting times. The students were beginning to get restless and short-tempered with each other, and I thought they could use an activity that would require them to work as a team. I was right. They absolutely loved it, and they learned to value all members of a team, regardless of academic skills or social stature.
You will love her advice on how to integrate STEM, STEAM, and Maker projects into your classrooms and homes!
