This document discusses telling time and writing time to the hour and half hour. It explains that a clock has two hands, with the long hand telling the minute and being called the minute hand, and the short hand telling the hour and being called the hour hand. It provides examples that when the minute hand is at 12 it is o'clock, and when the minute hand is at 6 it is half past, illustrating this with clocks showing 3 o'clock and half past 8. It notes that for stated times, the hour hand should be drawn between the stated hour and the next hour.
