Stamps Game

Today we did notes on Pathways and practiced the first question ( with Jason and Penelope ). We took notes on F.C.P. and we were supposed to do Factorial Notation but were doing that tomorrow. One of Mr. Maxs examples was: Calculate the number of ways to enter and exit the arena during a hockey game.
a) first period
ways in= 1
ways out=5
Therefore there are 5 ways in and out of the building.
b) third period
ways in=5
ways out=5
Therefore there are 25 ways in and out of the building.
