Divide circle into 4 quadrants
Create three “tick marks” in each quadrant
Name the “Big 4”
Start with the middle tick mark and count by fourths while hitting Big 4
Count the remaining tick marks by counting by sixths while hitting Big 4
Fill in first quadrant with coordinates and remember All Students Take Calculus!
