Some mummies were talking about different ways of teaching kids how to tell time. I only managed to dig up this game I bought a couple of years ago when I did my CNY spring-cleaning recently.
These are 12-sided dice, the red die has the numbers 1 to 12 for the hour hand and the blue die the numbers 00 to 55 in intervals of 5 for the minute hand. So all you've gotta do is roll the dice and then you move the hour and minute hands to the correct places. I can't remember if there were written instructions with ways to make the game more interesting, but this was how we "played" with the clock.
