What it is: Find Your Pi Day is a simple site from Wolfram where students can type in any number (like a birth date) and the site will tell you where that number falls within the Pi sequence. All dates fall somewhere within the first 10 million digits in the sequence. The place in the sequence is depicted by a spiral that goes in and out to display the beginnings and ends of such long digit sequences.
How to integrate Find Your Pi Day in your classroom: Find Your Pi Day is a neat site to generate conversation and inquiry into Pi. This is a fantastic place to begin exploration of Pi. Students can learn about the mathematical sequence and the science of Pi in this background Wolfram blog post.
