I'll be darned - we always did two-dimensional!  Since the side faces
should have certain specific numbers to go with the rolled number, how
about making lists of the "right" numbers.  I don't have any dice here
and I'm not going to take time to fine one, but e.g. if 6 is the real
number and 3 is on the left face and 4 is on the right face the list
would be [3 6 4]  Then you could randomly select a list on each roll and
using your inputs put the "correct" number on each face.  That way you
could use the procedures the kid already has since clearly he has it
worked out to put three different numbers on three different sides
already.
