One way that I help to make learning about circumference a little bit more entertaining is to go out and purchase bubbles for my class. We learn the formula and reasonings behind the circumference of a circle and then head outside. While there, I give each group of students a bottle of bubbles and have them blow away! As the bubbles are floating back to the ground, they are to catch them on construction paper. The paper soaks up the burst bubble and forms a circle. Then the kids measure the diameter and compute the circumference of that bubble circle!
