Some thoughts:
A. Define round as a way to get rid of the fractional part.
B. Use a simple (almost regular) polygon that can be multiplied to be bigger.
C. Create your own functions that hide decimal fractions and let students use
them.
1. Use turtle graphics
D. Draw a circle of diameter 100 on a grid and create a list of points to be
used for corresponding to degrees.
