New Year's Eve is December 31, the last day of the year. At midnight the clock reads 12:00 a.m. and a new year begins, so many people count down the last ten seconds together and cheer, and some watch fireworks. Midnight is the start of a new day as well as a new year: a time after midnight is a.m. again, on January 1.
Six pages that build from counting back to elapsed time. Page 1 has countdown strips from 10 to 0 and from 20 to 10: children write the missing numbers. Page 2 starts a hop at a dot on a number line from 0 to 20 and counts back, then writes the subtraction. Page 3 shows o'clock times in the evening on clocks and digital displays: how many hours until midnight? Page 4 reads a clock at an hour or half hour and hops along a time line to midnight. Page 5 has clocks at five-minute times with the minutes round the rim, for counting on by 5s. Page 6 is six New Year's Eve time stories, some crossing midnight. The first problem on every page is worked as an example.
Count down from 10 together, then from 20, with a hand going down for each number. Pages 1 and 2 suit 1st grade, pages 3 and 4 2nd grade, and pages 5 and 6 stretch to 3rd grade elapsed time. On pages 4 and 5, show how counting on to the next hour first and then the whole hours makes the jump to midnight easier.
On New Year's Eve, look at the clock together through the evening and ask how long is left until midnight. Count down the last ten seconds out loud, and the next morning talk about why the clock says a.m. again.
