Freehand Circle Drawing Competition
Challenge your students to freehand draw a perfect circle on a sheet of paper or on the class' chalk board. Have the class vote on the winner.
Have the class add a radius line and then extend it to become the diameter to familiarize those terms. Use a compass to trace a more accurate circle overlay to familiarize students with the compass. Use pi to calculate the area of each student’s circle under the assumption that it was perfectly drawn.
