January 31, 2007
My student advisory group enjoys our “Today’s Date/Equation Challenge.” Our rule is to keep the numerals (or factors of them) in the order that they appear in the day’s date, creating an equation. Operational signs and equal signs are to be inserted between digits.
- January 19, 2007, can be written as: -1-1+9=07 (1-19-07)
- December 3, 2006: 1+2+3=06 (12-3-06)
- November 23, 2006: (1x1)x(2x3)=06
I leave these equations on the board throughout the day. Students get really excited about this challenge.
