Objective
Students use a calendar to solve math problems.

Directions
Show students a calendar in the classroom or the calendar shown below. Tell them that this is a typical calendar for one month:

Sun. Mon. Tue. Wed. Thur. Fri. Sat.
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31

There are always seven days in a week. A week will often continue on to the next month. Any day of the week–such as a Sunday–is always seven days after the previous Sunday and seven days before the next Sunday.

These months have 30 days:
April
June
September
November

These months have 31 days:
January
March
May
July
August
October
December

(Note: February has 28 days except leap year when it has 29 days.)

Years
Look at the following information about years:
1 year = 12 months
1 year = 365 days
100 years = 1 century
1 year = 52 weeks
10 years = 1 decade
1,000 years = 1 millennium

Leap Years
Leap years are scheduled every four years on years ending with a multiple of 4. Leap years usually coincide with presidential election years in the United States. A leap year has 366 days. Leap years are not scheduled for the first year of a century unless the year is divisible by 400. The year 2000 is evenly divisible by 400 and thus is a leap year. The year 1900 is not evenly divisible by 400 and thus was not a leap year.

Recent Leap Years
1992
1996
2000
2004
2008

Have them use the calendar to solve the problems on the activity sheet.
