The match stick problem.

Today, our teacher gave us a challenge and we had to complete it. This was the challenge-
What we had to do was move three match sticks to make five squares. This is how to do it-

This is the first move. That makes one more square.                                This is what you do next.
                                         

Move 1

Move 2

Then do this, you might think that it is only 4 but the one on the outside is one as well.

Move 3
