The same clock time can happen twice a day. This 3rd grade am and pm time worksheet helps your child tell the two halves of the day apart, a.m. and p.m. A timeline at the top shows the 12-hour clock: the a.m. hours run from midnight to noon, and the p.m. hours run from noon to midnight. Then come five short stories from daily life. Joan eats breakfast at 7:00, Beth sets the table for dinner at 5:30 and Paul eats lunch around noon. Charity comes home from school at 4:05, and Mom leaves for work at 7:30. For each one, your child ticks a.m. or p.m., and the second page is an answer key that explains the first event.
