March 14 (i.e., 3/14) is also known as Pi Day.
Pi, which begins 3.14, is a number that has long fascinated people, as it keeps going and going and going. In other words, it’s a number we can’t even fully describe, yet at the same time, it’s useful in an amazing number of situations (including in helping us measure circles).
Pi reminds us of our limited knowledge (we can’t even fully describe parts of God’s creation) and should cause us turn in awe and wonder at God’s greatness!
Yet instead, many get lost focusing on the number pi itself–worshiping the creation rather than the Creator (Romans 1:20-23).
For more thoughts on pi, check out “Thoughts on Pi,” as well as this lesson from Principles of Mathematics. They both have information you could share with your students now or whenever you cover pi; you could also have students apply pi themselves by finding the circumference of a few circles…or, for older students, by using one of the many physics formulas that utilize pi (see this Wikipedia list for ideas). Update: NASA has put together a Pi Day Challenge that shows just how useful pi is! Note that NASA does not come from a biblical worldview, so please use discernment (while most problems looked great, one at least hinted at finding life on other planets).
When looking at pi or any area of math, remember to point students to the Creator and not to the creation itself.
