In small groups of 3 or 4 each student will be given 2 circular store bought cookies (oreo, chips ahoy, nilla wafer, ect.) Students will measure the cookies diameter and circumference. They will plot on graphical analysis and derive an equation EX: C= 3.14(in/in) d. Students will also answer evaluation questions about radii about the circle (cookie) and rotating the circle for circumference. Here I plan to use a chips ahoy cookie and the printed measuring tape on the back so students can rotate
