Mathematics In the classroom
Students will learn the many applications of lenses and the instruments that use them. They will understand the effects of refraction when light passes through a medium more dense than air and how it results in the properties of lenses. They will also become familiar with the properties of converging lenses and will investigate the formation of an image produced by a converging lens.
Symmetry and Tessellations
This unit begins with polygons and pattern blocks, works with rotational, translational, and reflective symmetries, experiments with tessellations, and finishes with the creation of an Escher-like tessellation.
