Description

There are many ways to make polyhedra from paper without scissors or tape. Sonobe polyhedra are a great first method to learn. Sonobe polyhedra are easy to make and put together, require a relatively small number of modules to achieve impressive results, and can be used to construct an amazing number of different polyhedra.

Levels

• Grades 2 through 12.
• Adults will find this activity interesting.

3.G.1	Understand that shapes in different categories may share attributes and that shared attributes can define a larger category. Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
4.G.1	Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
4.G.2	Classify two-dimensional figures based on parallel/perpendicular lines or angles of a specified size. Recognize right triangles as a category, and identify right triangles.
4.G.3	Identify whether a plane figure is symmetric about a line and be able to draw the line of symmetry if so.
