Sierpinski's Carpet
Exploration Questions

Run several stages of the Sierpinski's Carpet Activity, and answer the following questions:
  • Fill in the table:
    Iteration 1 2 3 4
    Number of Shaded Squares
        
        
        
        
    Area of one Shaded Square
        
        
        
        
    Total Shaded Area
        
        
        
        

  • What patterns do you see in the numbers for the number of shaded squares? Can you build a formula for the number of shaded squares at the n-th stage?

  • What patterns do you see in the numbers for the area of one shaded square? Can you build a formula for the area of one shaded square at the n-th stage?

  • What patterns do you see in the numbers for the total shaded area? Can you build a formula for the total area at the n-th stage?

  • What do you think happens to these numbers as the number of stages approaches infinity?

  • Compare these results to those for the Sierpinski's Triangle. Does the "three-ness" of a triangle and the "four-ness" of a square seem to play a role in these numbers?
