      I understand what you're asking for, but if I used higher numbers I would have to have many many counters. Just to do 9 x 9 I would need 81 counters that are all the same. To do 12 x 12, I would need 144 counters. But, if you understand the concept of using arrays, you can draw dots, use coins, little rocks, or anything else that you can find around your house to make your own or arrays. :-)

      Huda Quadri, you could try watching the video again? We count the amount of counters going across the top row, then we count the number of counters going down the left side and we can multiply them to find how many there are. Five going across and two going down is 5 X 2 = 10 counters in all. Did that help?
