Belated Pi day

We looked at he relationship between diameter and circumference todah

We made a graph showing all of our class data

We noticed it is linear, positive and shows a strong correlation.  We can use a line of best fot and interpolation and extrapolation to solve problems.

We also noticed that the rate of change is 3.14 (perfect for pi day)

We sang a pi day song (to the tune of oh christmas tree) and talked about irrational numbers.

And finally ate some pies!
