What do pentominos have to do with geometry?
Identifying Pentominos
Cynthia Laniusí lesson which is linked below is an investigation of pentominos. She starts the lesson with of a definition of polyominos and then develops a specific investigation of pentominos. Make sure that you understand what a pentomino is, and what is not. How do reflections, rotations, and translations of the pieces effect the number of pentominos? Go to Cynthia Laniusí lesson to find out what pentominos are.

Once you have a clear definition of what a pentomino is download this
and print it. See if you can draw or cut out all of the pentominoes (there is a finite number).

Once you have cut or drawn out the set of pentominos, download this
solution key to see if you have drawn them all.
