When I was shopping for birthday gifts for my brother (a math major), I started coming across T-shirts for Ultimate Pi DayPi Day is celebrated on March 14 (that is, 3.14).  This year, you can take it even further because the year makes it 3/14/15 (five digits of pi).  Some people are even making special plans for 53 seconds past 9:26 (3.14.15 9.26.53 or 3.141592653, 10 digits of pi).  Here are a couple of books to help children learn about the number pi and why it’s important:
