Lesson 2

Regular Tessellations

View Student Lesson

Lesson Narrative

In this second in a sequence of three lessons, students look at regular tessellations. Two polygons in a regular tessellation must

  • not meet at all or
  • share a single vertex or
  • share a single side

Students show in detail that triangles, squares, and hexagons give the only possible regular tessellations.


Learning Goals

Teacher Facing

  • Justify (orally and in writing) that regular triangles, squares, and hexagons are the only regular polygons that can be used to create a regular tessellation.

Student Facing
