For this week's Top Picks List Friday, we are featuring great geometry apps, games, and websites in honor of Pi Day. For those not familiar, PI Day is an annual celebration commemorating the mathematical constant π and is observed on March 14th because 3, 1, and 4 are the three significant digits in the decimal form of π. This list is a collection of great tools to use with your geometry students. Whether you're teaching explicit skills or encouraging exploration and play for conceptual development, these tools can help your students' geometric knowledge really take shape.
