3: More Tessellation

The next week we had to make our own tessellating shapes. We got a box of 2D shapes to see if they fitted together. Some shapes fitted together without any gaps, and some did not.

ODid tessellate:
Square
Triangle
Rectangle
ODid not tessellate:
Circle
Pentagon
Octagon

Then our teacher showed us a trick. If you get a square shape and cut it into two pieces and sellotape it back to back and draw around it, you see that it will tessellate. We made lots of tessellation shapes this way. You can see two of them here.
