Andrea Palmer
Somerville, MA
Environment: Urban
 
Big Idea:

Make an estimate for the area of each circle. How can we calculate a more exact area? Students develop an estimate for a circle’s area and learn the formula. Then students must apply their knowledge to determine whether they calculate area or circumferen
