### Odd Day in the Math Classroom

Odd day is a day that singles out those wonderful, wacky odd numbers. It occurs when three consecutive odd numbers make up a date — something that happens only six times in a century.

The last Odd Day was 09/11/13 and this year it will occur on 11/13/15. Can you guess when the next one will take place? (Not until 1/03/2105.)

Celebrate the day by doing odd things in your classroom.

You may want to let your students do odd numbered problems on this day, count off by 3s, wear odd outfits, have a crazy/odd hair day, recite an odd poem or quote some odd trivia.

Your students could play Dominoes or Go Fish or Mancala (board games or computer games) but count up only the odd numbers left at the end.

Or let the students play board games where players can only move when the dice shows (or totals) an odd number.

Try a few odd math facts, skip-count by odd numbers, etc.

Then let your students figure out when the previous four Odd Days occurred (3/5/2007, 5/7/2009, 7/9/2011, 9/11/2013) and when they can expect to see the next four Odd Days. (1/3/2105, 3/5/2107, 5/7/2109 and 7/9/2111)
