3DVinci presents a collection of mathematics projects that students can do using Google SketchUp. If you've never used SketchUp, don't worry. 3DVinci hosts video tutorials that will show you everything you need to know to get started using Google SketchUp to teach mathematics.

Margaret Wertheim leads a project to re-create the creatures of the coral reefs using a crochet technique invented by a mathematician -- celebrating the amazements of the reef, and deep-diving into the hyperbolic geometry underlying coral creation.

ourteen units of study based around instances of mathematics concepts, including fractals, basic Algebra, and Geometry concepts occurring in cultural designs. The units of study can be used with middle school and high school students. The resource page for teachers provides some additional resources and background information.

In addition to looking at art and architecture, we'll cover any mathematics-related topics as we go along. The Math Topics for the first unit will be an introduction to the triangle in general, and the so-called Egyptian triangle, contained in the great pyramid. Since the Egyptian triangle contains the golden ratio, we'll introduce the ideas of ratio and proportion here, and for squaring of the circle, we must be able to find perimeters and areas of the square and the circle. The plan is to go more or less chronologically, following threads of Art, Mathematics, and Architecture, from Egypt to the present.

Transformation Golf. The directions are "Get the blue shape to match the green shape." Shots are taken by commanding your dynamic geometry software to perform line reflections, transformations, rotations, and dilations on the blue shape. The early holes start with one-offs, and later holes require compositions of transformations
