How To Play Geometrics Bingo

  1. Print out your free Geometry bingo boards, or make custom ones with Bingo Card Creator. Click here to get started.
  2. Give one card to each player.
  3. Call off words randomly, for example by using a call list. You can either just say a word, like "obtuse angle", or you can make up a more involved clue involving obtuse angle.
  4. When a word is called, each player should find it and mark it.
  5. The first player(s) to clear five words in any direction (horizontal, vertical, or diagonal) wins a small prize.

Notes: How long a bingo game lasts depends on what pace you read the clues at and how many players you have. If you read faster, such as for older or more experienced students, or if you have more players, the game tends to end more quickly. In general, I suggest allocating between twenty and thirty minutes to a bingo game. Since they can potentially end as early as the fourth word called, though that is quite rare, I encourage you to keep playing in the event of the game being over earlier than you expected it to be. Almost 90% of bingo games with a 25 word list and 25 players will see their first bingo within 7 to 11 words being called.
