Clocks have hands that tell us what time it is. This lesson shows clocks that are set to the "top of the hour". One o'clock, two o'clock, three o'clock, etc. O'clock means "of the clock". The appostrophe replaces the missing letter f and the word the. One o'clock can also be written 1:00. (3-page lesson)
