I've been teaching our 5th grade Design + Code + Make class for a few years and have developed a few units/projects involving cardboard construction, robotics (with Hummingbird Bits), 3D printing, video game design (MakeCode Arcade), and vector drawing/laser cutting. I'm happy to send you some plans if you want. Here's one project I presented at the Fall CUE Conference in case it's helpful:
I see each of my 5th grade sections about 23 times over the course of the school year and we finish 3 projects. Right now, I have them building a greenhouse which has been pretty fun. They love using the drills and drivers.
