K-12 educators and students from all over the world use SketchUp to explore, explain and present their ideas using 3D models. SketchUp users in K-12 Education can choose between Google SketchUp (the free version) or SketchUp Pro (which is free for educators and extremely affordable, or in some cases granted, for students and schools).
