| My son is a 5th grader and came home with a math question that I can't answer. The question stated - "Write the array for 3" I don't understand how this can be done with just one number. Can someone explain. Thank you.

Jamie, An array is a rectangular arrangement. We have received questions like "draw four possible arrays for 72 marbles". One such array might be 9 by 8, that is 9 rows and 8 columns, or 6 by 12. The array might also be 72 by 1, 72 rows and 1 column. For the number 3, since it is only divisible by 3 and 1, the array must be 3 by 1 or 1 by 3. Penny |
