From: Nancy To: Teacher2Teacher Public Discussion Date: 2009100421:49:37 Subject: Re: Re: arrays We use arrays as early as 3rd grade, when introducing multiplication. 2 rows of 6 in each row would introduce the concept of multiples of 12. Just as 1 row of 12, 3 rows of 4....therefore the multiples of 12 are: 1,2, 3, 4, 6, and 12.
