How I Use It
I'm a personalized learning teacher, so I am constantly overseeing student-led and driven projects. Recently, I've been using Tinkercad more and more for everything from making 3D blueprints and actually building those designs in real life to simply having students build Minecraft characters or landforms. You could easily integrate it into any STEAM activity. It would be a phenomenal tool for actual application of Geometric figures.
Don't let the Grades 6-12 tag fool you. I use Tinkercad on a daily basis with kids as young as 1st grade and they have mastered it and utilize it with ease. It's a super powerful program, intuitive and downright fun. The fact that it's browser based only seals the deal for me.
