Want to teach geometry at home or in a classroom with 3D prints, coding, or some other hands-on exploration? Geometry, of all the branches of mathematics, is the one that is most easily visualized by making something. However, it is all too easy to reduce it to reams of formulas to memorize and proofs to replicate. Our new book, MAKE: Geometry
, helps students learn key topics from middle- and high-school geometry by creating 3D prints and trying out other hands-on projects. The book also teaches how to use the free CAD program OpenSCAD, which uses computer code to describe objects. This interactive workshop will introduce teachers and parents to OpenSCAD and the models in the book, and help them feel confident using the materials and expanding on them. No prior knowledge of OpenSCAD is required!
