I have used this lesson with grades 3-5 and everyone is amazed at some of the awesome works of art that my students have created. It includes an art history lesson on artist M. C. Escher, who is widely known for his use of tessellations as an art form. The project involves taking a simple geometric shape (a square) and turning it into a non-geometric shape that will tessellate across a plane (a piece of paper) without overlapping or leaving any gaps. (Its like a jigsaw puzzle where all of the pieces are the same shape.) Your students will then look at their shape and decide what it looks like, then draw and color the image across the page. I have included several examples of my student's work to help your students visualize what a completed tessellation might look like.
