It is quite similar to my old building a clock worksheet. So the description will be nearly the same. I just found out, that a little change makes teaching how to tell the time less difficult. The change is that the hands have eyes. Colour on each hand the right eye in the colour of the fields 1 to 6 and the left one in the colours of the 7 to 11 fields. Tell your pupils that the big hand has control of the eyes (of all hands) depending if it is in the "past" or "to" part.
In the past part the past eye is open and looks backwards. The to eye looks forward. Corresponding colours makes reading the clock easier.
