Which numbers will you mark on which dice so that you can easily depict all the dates of the month?
Dice one will have the numbers 0, 1, 2, 3, 5 and 7.
Dice two will have the numbers 0, 1, 2, 4, 6, and 8.
You must be wondering why there is no face with a 9 in it. This is because you can always turn a 6 upside down to make it a 9.
