teaching pi

I'm in the process of mentoring the midPOW for 2/26 and an
understanding of pi is important to understanding how to solve the
problem. However, I'm finding out that the overwhelming majority of
the students who have submitted, seem not to know that although
C = pi * d, C is approximately equal to 3.14 or 22/7 * d. I'd like to
know how the textbooks handle this. My school's text makes this
distinction and I have always taught it, but my experience with this
POW has shown that most students think that pi is equal to 3.14. How
do others handle this topic?
