Get youngsters comfortable with telling time on both analog and digital clocks. They match times to the clock faces, all of which read a time on the hour or half-hour. The times are written out here (i.e. "half past nine" or "9 o'clock"), so decide if this is your specific objective. An added challenge could be for kids to write out the all-numeric version for each of these. There are 12 times here and four have been completed as examples.
