Tomorrow is March 14th, also know as Pi day! Every year many teachers observe the coincidence that our calendar notation aligns with the most famous ratio – the circumference of a circle to its diameter! Thinking about ways to incorporate Pi day into your classroom? You can start by providing a overview with the BrainPOP Pi Movie , continue by checking out BrainPOP Educators Superfaux2’s custom mixer quiz on Pi, or create your own. Check out our “lesson ideas” page for some ideas about creating a Pi Day festival from Educator Toni Sexton. Have a piphilologist contest, to see which student can memorize the longest stretch of numbers! Have additional ideas? Share them below. Happy Pi Day!
