My 4th grader has started working on rectangular array that shows 2 factors of a number.

The problem reads on centimeter grid paper draw as many arrays as you can for each of the #'s 2,3,4, 5,6,7,,11,12,15 and 16. That would be great except I have no idea what they are talking about and I cannot offer any help to my daughter.

Susan pose la question :
I'm a lawyer but evidently incredibly stupid at 4th grade math. . . .Question: cover a tabletop with 9 rows of square tiles with 9 squares in each row. How many tiles cover the tabletop? Then, the paper shows a 9x9 array and asks how it is used to solve the problem. My daughter wrote 9x9=81. The next question is "what are the products of the two smaller arrays?" ???? There are no other arrays - are we to make smaller arrays from the 9x9? how?

Arrays of chairs 2009-01-08
Vickie pose la question :
I am not sure how to help my son figure out one of his math journal problems. He is in third grade and this just seems a bit much for him. They have only been working on multiplication for about 3 weeks and just went back to school from Christmas break. Their other homework has been about arrays, so I guess his teacher wants this answered in some sort of array. Unfortunately I'm not sure.

The problem states: If you have 24 chairs find the total number of ways the chairs can be arranged.
