Tessellation #3: Free-form
To make this tessellation, students start with a square (just the outline), and then drawing a couple sides, copying and pasting them into the right place. Making it work is a challenge!
Tessellation #4: Horse/Animal
To make this tessellation, students start with a filled rectangle, selecting a piece from one side, sliding it to the other; selecting a piece from the top, sliding it down. Then adding creative details, depending on what you see in the shape.
