Hello Michelle, Rather than define "array," let me give you some examples. The number 12: ************ 1 by 12 *** 4 by 3 * 12 by 1 *** * ****** 2 by 6 *** * ****** *** * * **** 3 by 4 ** 6 by 2 * **** ** * **** ** * ** * ** * ** * * To make life simpler, we usually tell students to consider the following pairs of arrays the same: 1 by 12 & 12 by 1 2 by 6 & 6 by 2 3 by 4 ^ 4 by 3 So 12 has 3 different arrays. When I have students make arrays, I have them use pennies, or bingo chips or little square tiles. Hope this helps. -Jeanne, for the T2T service
