This is a preliminary report on design features of large, light-weight, modular equilateral triangles and classroom activities developed for using them. They facilitate the fast teaching of three-dimensional geometry together with basic math skills, and create a lasting motivational impact on low achievers and their subsequent performance in math and science.
