I interviewed in Austin, TX and was asked:
"There are two children, 5 and 6 year olds who understand addition and subtraction. They do not understand multiplication or division. How would you explain the concept of prime numbers to them?"

Take 11 (prime number) objects and ask the children to split the objects into 2 groups with the same number of objects in each. Repeat the process and ask the children to split the 11 objects into 3 separate groups. There will always be one group with an extra object.
