Help your students celebrate Pi Day, 3/14, while engaging students in rich problem solving and explorations. Here is a list of some of our favorite resources and ideas for K–12 students.
- There are many fun and innovative ways to celebrate Pi Day in your classroom and beyond—you probably already use it as a jumping-off point for key mathematical lessons. If you’re in need of something to invigorate your tried-and-true Pi Day traditions, NCTM has you covered! Here is NCTM’s collection of K–12 ideas for Pi Day.
- Challenge students to measure the diameter and the circumference of circles. Here is a TIMS Project lesson: Diameter vs Circumference. Put the data into the Desmos table/graph and ask students to describe the relationship between the two variables. This Desmos activity: Measuring Circles connects proportional reasoning and Pi in a similar way.
- The Grazing Goat Problems do not disappoint. Here are some in Desmos Activity Builder. https://teacher.desmos.com/activitybuilder/custom/5e9f37f746c19a0ca823f189
- This Desmos activity: Measuring Circles authored by Kate Nowak connects proportional reasoning and Pi.
- Students solve area and circumference problems in this Desmos Activity: Donkey Kong Circles authored by Kurt Salisbury.
- Here is an entire unit of problem solving with Circles. It’s a great way to engage students in multi-step problem solving and algebraic reasoning with lots of fun problems.
