Section 3 - Working with Shapes

Polyominoes are simply patterns made from squares

a. Making squares

b. Rule for playing with polyominoes

c. Making patterns
Question: Make as many different patterns as you can with two squares (called Dominoes). Remember the rule!
Question: Make as many different patterns as you can with three squares (called Trominoes) Remember the rule!

There is only one different pattern possible with two squares.
There are two different patterns possible with three squares.

Where you right?

Question: Make as many different patterns as you can with five squares (called Pentominoes).
Question: Make as many different patterns as you can with six squares (called Hexominoes).

d. Areas and perimeters of polyominoes
