Need an engaging math activity to celebrate Pi Day? This fun project will have students working with circumference, area, and circle properties while creating a big sign! Students color the false statements and create a 27” by 35” collaborative poster that reads “Happy Pi Day!”Here's how it works: 16 pieces are provided with various statements about circles and pi. Students can work in partners or individually. They fill in the areas with false statements and leave the true statements white.
