teaching pi
Posted:

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?
