This String Shapes lesson plan also includes:
You'd never have guessed it, but simple pieces of string make a fabulous manipulative for the study of geometry! In the fine instructional activity here, young mathematicians use string to make a variety of polygons. Pupils sit in various configurations and make triangles, squares, rectangles, and other common shapes. Important vocabulary such as vertex, angle, side, and, length are introduced. I love the simplicity of this dynamic and valuable educational resource.
