How to play Pi Day bingo

  • Print one card per student and one call sheet for the teacher or a student helper.
  • Give each player markers, or better yet, pie-shaped cutouts or round candy.
  • The caller reads words in random order and crosses them off the sheet.
  • The first player to complete a row, column, or diagonal calls bingo and wins.
  • For a longer game, play four corners, a plus sign, or full blackout.

Turning math class into a celebration

Pi Day falls on March 14 because the date, 3/14, matches the first digits of pi (3.14159...), an irrational number that represents the ratio of a circle's circumference to its diameter. This bingo game reinforces geometry vocabulary like radius, chord, and tangent while keeping the mood light with pie-related words and fun facts, like the holiday sharing a birthday with Albert Einstein.

Consider pairing the game with a pi-digit recitation contest or a slice of actual pie for the winner.

Make it your own

Adjust the vocabulary level for your grade: younger students can focus on basic shape and circle terms, while older students can include trigonometry and formula-based words for a more challenging round.
