 
Hi Laura, I'm going to change the problem slightly.
I would rewrite Larry's division sentence as a multiplication sentence. That is I would rewrite 15/5 = 3 as 5 × 3 = 15 or perhaps 3 × 5 = 15. I can draw arrays for these sentences,
The first is a 5 by 3 array and the second is a 3 by 5 array. (Mathematicians always write the number of rows first and the number of columns second.) Thus my response to the question about Larry's array would be to say it is either a 5 by 3 array or a 3 by 5 array. I hope this helps,
