The Paper Folding ActivityPart I: Number of Sections1. Fold an 8.5 x 11" sheet of paper in half and determine the number of sections the paper has after you have made the fold.2. Record this data in the table and continue in the same manner until it becomes too hard to fold the paper.

4. Determine a mathematical model that represents the data using the calculator.To run an exponenal regression do the following:
1. Turn the “Diagnosc ON” ‐‐‐‐Push 2 nd then 0 and scroll down to the “Diagnosc On”.
2. Push Enter
3. Push “STAT” then “EDIT”
4. Enter the x and y values.
5. Push “STAT” then go over to “CALC”
6. Select the “ExpReg” opon and push “Enter”
7. Write your equaon in the form y = ab x
a =
b =y =

5. In your model, y=a(b)x, what value do you have for a? What does that seem to relate to when you consider your data? When x=0, what is your function value?
6. What is the value of b in your exponential model? How does this value relate to the data collection process?

One glove per person
Only touch M&M's with glove hand!
Keep M&Ms in trays (NOT ON FLOOR)
Only eat M&Ms without M or your data will be wrong :(
