Halloween Math Activities

Turn the Halloween season into an opportunity to do some math activities! In this module, you'll find a clever collection of arithmetic, algebra, and geometry activities.

  1. Geometry activity: Watch a video about how spiders build webs and analyze the result geometrically. Students build polygon-based web designs in this hands-on activity.
  2. Algebra activity: Going to the pumpkin patch? Use different sized pumpkins on this data-gathering activity, where students measure diameters and circumferences and graph the results. 
  3. Arithmetic activity: Two addictive divisibility games based on whack-a-mole.
