Hip, Hip, Array!





We have been exploring arrays!


Row x Column = Product




When the factors were different digits, the arrays were in the shape of a rectangle.



















































































When the factors were the same...look what shape it made!


















Can you name one square array that is missing?

Do you see any arrays in your home?

Tell us about it in the comments!

  1. Dear Mrs. Ranney,

    I found an array on a calendar in my house. It has 5 rows and and 7 columns. 5 x 7 = 35. A square array that is missing is 2 x 2. It's very fun to make an array!

  2. Dear Mrs. Ranney,
    I found an array in my house too! One array that is in my house is 5 rows of 2 columns of knobs on my parents drawers, which is obviously 5 x 2 =10. An array that is missing is 5 x 20=100. Arrays are awesome!!!!!

    One square array that is missing is 6x6=36. In my house there is an array of 2x1=2. This array has 2 rows and 1 column. I think looking for arrays is the best!!!

  7. Dear Mrs.Ranney,
    I found an array in my kitchen. The windows make 5 rows of three. I'll give you the multiplication problem. Here it is, 5x3=15. One square array missing is 9x9=81. Arrays are awesome!

  8. Dear Mrs. Ranney,

    One square array that is missing is 6x6=36. In my house there is an array of 2x1=2. This array is 2 rows and 1 column. It is in my mom's room, and they are closet door mirrors. I think arrays are the best.

  9. Dear Mrs. Ranney,
    I have seen an array myself. 3 x 3 = 9. I found it on the keyboard of my computer. It is interesting that I found an array while I was typing. This array is cool, because everyone can see it. You can find it right above the arrows keys.

    One square array that is missing is 10x10=100.
    I've had a great time identifying arrays. One array in my house is 2 rows of 4 lights which equals 8. I found this on the ceiling of my living room.

  11. Dear Mrs. Ranney,

    The array that is missing is 100x100=10,000. I found an array that was 5x8=40. It was the window
    I think arrays are cool because you can count rows and columns.

  12. Dear Mrs. Ranney,
    The square array we missed was 11 x 11 = 121! I found another array in my house. It's on my great grandmother's secretary. It's 3 drawers that have 2 handles on each drawer. The factors are 3 and 2.

    3 x 2 = 6

    Sincerely,

  13. Dear Mrs. Ranney,

    An array I found in my house is 5x7=35. I was wondering if you have an array at your house? One square array that's missing is 12x12=144. Arrays are very interesting to me:)!

    Sincerely,

  14. Dear Andy,
    Thanks for asking about arrays in my house. I've been looking around for an array that I thought would be particularly interesting, and I finally found it! In my living room there is a set of shelves holding a collection of CDs. There are 7 shelves that each house 40 CDs. That is 7 rows of 40, or 7 x 40 = 280. I Notice that you didn't describe where you found your 5 by 7 array. How about adding a comment about that?
    Sincerely,
    Mrs. Ranney
