Clocks are two clocks on top of each other. The minute hand is not pointing at the 3. It is pointing PAST the 3 to the 15 minute mark on the other side. The way I taught it was to have kids write their numbers around a blank circle with tick marks on it from 0 to 59. We did this 6 times until everyone could do it without telling them it was a clock. When I introduced the clock to them, they were used to reading numbers around a circle, because they had to write them that way.
