Leap Year Math

What Is a Leap Year?

A leap year (or intercalary year) is a year containing one or more extra days (or, in case of lunisolar calendars, an extra month) in order to keep the calendar year synchronized with the astronomical or seasonal year. For example, February would have 29 days in a leap year instead of the usual 28. Seasons and astronomical events do not repeat at an exact number of full days, so a calendar which had the same number of days in each year would over time drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year which is not a leap year is called a common year. Source: Wikipedia

Are you getting ready for the holidays? You can still fit in some family math into your busy schedule. There's something here for all ages!

Holiday Calorie Count

Are you eating more than normal? I know I eat more chocolate over the holidays!

Try tracking what you eat and your activities for the day, charting the calories consumed and burned. This requires both measuring and arithmetic.

Demonstrate your results on a bar graph. This is a great time to also discuss nutrition and health. Do candy canes count as a red vegetable?
