View Resource : Train Times: 12-Hour and 24-Hour TimeA free Grade 3 math worksheet on using a calendar during the December countdown: days of the week, months of the year, counting on in weeks to find dates, working out how many days are left until a date, finding the day of the week after a number of days and converting weeks to days. Includes a timed lesson plan, a six-activity worksheet with 26 questions, an editable Word version and answer key.
Children use a December calendar to answer real countdown questions. They learn that a week has 7 days, that December is the twelfth month with 31 days, and that adding 7 to a date gives the same day of the week a week later. They find the day of the week for later dates, work out how many days are left until a holiday, find the day of the week after a number of days and convert weeks to days and days to hours. The activities build strong calendar and reasoning skills that children can use every month of the year.

Support: give a printed calendar to count on. Challenge: children work out what day of the week January 1 will be if December 31 is a Thursday, and plan a 10-day holiday countdown.
Activities 1 to 5 check calendar facts, date reasoning and conversions (answer key included). Activity 6 shows whether children can explain their reasoning.
Show the trick that the same day of the week repeats every 7 days, so December 1, 8, 15, 22 and 29 are all the same day. When counting days between dates, remind children to subtract the dates rather than count both ends.
