Start by knowing the number of counters (4 x 4 = 16).
To make an array of more than 1 counter in a row, you want to find the factors of 16.
You know that the factors are 1,2,4,8,16, but since you are not allowed to have an array with only one counter, your choices are 2 and 8.
So the answer here would be 1 array with 2 rows of 8 counters and a second array with 8 rows of 2 counters.
This is just another way to teach factors.
