Mathematics Problem Of the Week

Spring 2005

POW 6: Right handed dice

You may know that opposite faces of a dice add up to 7, but did you know that there are two different types of dice? Here are two dice, a right-handed one and a left-handed one:

right-handed and left-handed dice


Decide whether the dice below are right-handed or left-handed:

die with 5 on top face, 1 on near face, 3 on right face.  Die with 3 on top face, 2 on near face and 6 on fight face

Now try these - they are more difficult.

Die with 6 on top face, 5 on near face and 3 on right face.  Die with five on top face, 6 on near face and 3 on right face


Don’t forget to justify your answers!
