Place Value

Today we began to look at numbers and the value of digits in a number. I used the metaphor of stadium seats (Note: Mr. Rodger’s idea.). Many of you know your position in a stadium determines the value of your seat. If you could choose 2 seats at Safeco Field for a game, based on the picture below, what would you choose? Think about the seats you picked and choose 2 new seats with a higher value. Last, pick 2 seats that would have a value less than the starting tickets. Can you describe how the position in the stadium affects the value of the ticket?

Now let’s think about that in terms of a number. Which number below has the greatest value? Which has the smallest? How does the position of the digit affect the value of that digit?
