Objectives: [NCTM Grade 68 Standards: Geometry, Reasoning and Proof, Communication and Connections]
 To manipulate triangles, squares, hexagons, trapezoids, and rhombuses to see how they might combine to form patterns in the plane.
 To consider which of these patterns are tessellations and which are not using the definition that a tessellation is a tiling with shapes that cover the plane without gaps or overlaps.
 To consider which of these patterns are regular tessellations and which are not using the definition that a regular tessellation is a tiling with shapes that cover the plane in a regularly repeating pattern without gaps or overlaps.
Materials  Activity pattern blocks including:
Procedure:
 Instruct the students to make patterns with the blocks, making certain that they leave no gaps or spaces.
 After each student or group of students has a pattern, have all of the students rotate around the room to view each others' products.
 Discuss the patterns.
 Discuss the relationships between the blocks.
Questions:
 Which shapes fit together easily?
 Which shapes don't seem to fit with the others?
 Which patterns could be repeated over and over again in the plane?
 What shapes fit together making a pattern using only one type of block?
 What shapes fit together making a pattern using two blocks that are different?
 What shapes fit together making a pattern using three blocks that are different?
