  Building blocks and tiles are an excellent way of learning about geometry and
mathematics in general. There are several versions of tiles that are either
snapped together or connected with magnets that can be used to introduce topics
like volume, tessellations, and Platonic solids. However, since these tiles are
made of hard plastic, they are not very suitable for creating hyperbolic
surfaces or shapes where the tiles need to bend. Curvagons are flexible regular
polygon building blocks that allow you to quickly build anything from
hyperbolic surfaces and tori to dinosaurs and shoes. They can be used to
introduce mathematical concepts from Archimedean solids to Gauss-Bonnet
theorem. You can also let your imagination run free and build whatever comes to
mind.
