Tessellations!!!!!
A tessellation is a way to tile a floor (that goes on forever) with shapes so that there is no overlapping and no gaps
Tile floors and puzzles are all tessellations, but these are not the only examples……
They are all around us
Where have you seen Where have you seen tessellations in your life?tessellations in your life?
REGULAR TESSELLATIONS:
RULE #1: The tessellation must tile a floor (that goes on forever) with no overlapping or gaps.
RULE #2: The tiles must be regular polygons - and all the same.
RULE #3: Each vertex must look the same.
What's a vertex? where all the "corners" meet!
. A fact: all polygons with more than six sides will overlap! So, the only regular polygons that tessellate are triangles, squares and hexagons!
SEMI-REGULAR TESSELLATIONS:
These tessellations are made by using two or more different regular polygons. The rules are still the same. Every vertex must have the exact same configuration.
The artist MC Escher made art based on tessellations.

Make your own tessellation
•There are two shapes that you can make•Both start with a square of posterboard
Shape 1Shape 1
Cut a shape form one side of a tile, tape it on the opposite side directly across from the cut out.
Shape 1Shape 1
Cut the shape in half, then tape them opposite each other. This is your tessellating shape!
Shape 2Shape 2
Cut a square tile in half in the desired shape and tape one side to the other.
Shape 2Shape 2
Cut the newly made shape in half again in the desired way.
Take the top two pieces and move them below the bottom two pieces. Align and tape with the corners matching. This is your tessellating shape!

Shape 1. Start with a square. Cut a shape form one side of a tile, tape it on the opposite side directly across from the cut out.
Cut the shape in half, then tape them opposite each other. This is your tessellating shape!
Shape 2 Cut a square tile in half in the desired shape and tape one side to the other.
Cut the newly made shape in half again in the desired way. Take the top two pieces and move them below the bottom two pieces. Align and tape with the corners matching. This is your tessellating shape!
