Algebra - Fun with Calendars
Algebra - Fun with Calendars
Description:
In this activity, a volunteer picks four days that form a square on the calendar, such as March 17, 18, 24 and 25. The volunteer computes the sum of the numbers of the four days (in this example, 84). A simple calculation then "magically" uncovers the four dates. But why does the trick work? This can be the start of an algebraic investigation that should be accessible to most pre-algebra and algebra students. Suggestions are given to extend the activity for the students to develop their own calendar tricks. In addition to being quite a bit of fun, one possible outcome of the activity might be that students see the power of algebra in every-day life. Includes teacher's notes.
