7. What is a regular tessellation?!

8. A regular tessellation means a tessellation made up of congruent regular polygons. [Remember: Regular means that the sides of the polygon are all the same length. Congruent means that the polygons that you put together are all the same size and shape.] A regular tessellation means a tessellation made up of congruent regular polygons. [Remember: Regular means that the sides of the polygon are all the same length. Congruent means that the polygons that you put together are all the same size and shape.]

9. Examples!!! Triangle Tessellation --  Square Tessellation -  Hexagon Tessellation 

10. Your turn! – Side one Pick a REGULAR polygon. Pick a REGULAR polygon. Use a ruler to make the regular polygon you would like to tessellate! Use a ruler to make the regular polygon you would like to tessellate! Cut out your regular polygon. (make sure its big enough so you don’t need to outline a million of them, but make sure you can trace it at least 8 times Cut out your regular polygon. (make sure its big enough so you don’t need to outline a million of them, but make sure you can trace it at least 8 times Trace your regular polygon side by side to fill up the foot x foot piece of white paper. Trace your regular polygon side by side to fill up the foot x foot piece of white paper. **** Make sure there are NO gaps! Use only one shape!

11. Your turn – side 2! This time, you can tessellate any shape of your choice! Do this on the BACK of the same piece of paper! This time, you can tessellate any shape of your choice!

13. Coloooooor!!!! Now that you have the front and back outlined, pick one of the sides to decorate! Now that you have the front and back outlined, pick one of the sides to decorate! Make sure that each polygon or shape is easily outlined in your end creation! Make sure that each polygon or shape is easily outlined in your end creation! If you have time, color the other side as well! If you have time, color the other side as well!
