that is, four ways. At this level a certain amount of experiment [can we put them in rows of five? Let's try...] is encouraged. Informal looking for patterns is also good. You should be able to see how this ties in with factoring, equal division of candies, etc. Good Hunting!
Vickie, I would have your son experiment, as RD says, with physical objects. Perhaps 24 pennies or candies or Cheerios. The task is then to arrange them in rows so that each row has the same number of "chairs". When you find an arrangement (array) record it by writing it as RD did, (the number of rows) x (the number of columns). Penny
