Math CentralQuandaries & Queries


Question from Yesenia, a student:

Ray makes an array that has four rows of four counters. He wants to make two more arrays using the same number of counters. He wants more than one counter in each row. What two arrays can he make?

Hi Yesenia,

What might be confusing about this problem is that non-square arrays can be presented two ways. For example a 3 by 5 array and a 5 by 3 array are different.
