The original puzzle One must build a calendar with the faces of 2 dice. They must be assembled to produce the numbers from 1 to 31, always using
both dice (01). How will the digits from 0 to 9 be disposed on the 6 faces of each die ?
The Solution Another simple but tricky little puzzle, in a class with the Three Lights. We must evidently have the digits "0", "1", and "2", on each die, which leaves 3 places on each die, 6 places in all, but we have, unfortunately, 7 digits left to place. How long does it take to realize that "9" is an upsidedown "6" ?
Pedagogy Children should be encouraged to build their own dicecalendar, and use it, by replacing the dice each day. Little cards could be made for each month of the year.
