This simple project is a fun way to learn about circles and circle measurements as well as deepen an understanding of the number pi, making this a great activity for your Pi Day celebration!
There are 2 different pages included in this download. The first is for younger kids, just to introduce them to the vocabulary terms and then let them practice measuring diameter.
The second page is perfect for older kids who are capable of accurately measuring the circumference and diameter of circles, as well as dividing those to calculate an approximation of pi.
