Hip, Hip, Array!



We have been exploring arrays!

Row x Column = Product

The multiplication for the array above is
3 x 4 = 12
because it has 3 rows of 4.

When the factors are different digits, 
the arrays are in the shape of a rectangle. 
When the factors are the same digit, 
the array are a square!


We practiced making arrays ourselves!
First, we worked with tiles and created arrays like these:









Here are a few more. Do you know what is different and special about them?

 











************

 Then we got more creative!























Some of us even made arrays at home and sent them in!

Alexandra's Headband Array



Jules' Array of Shoes




Alex's Cupcake Array  

Can you tell us the multiplication problem that goes with it?


*********


Here's one from Frogger! Can you tell him how many
 rows and columns it has?
Do you know the multiplication problem that 
goes best with Frogger's array?

 


***********



Here is a quiz about arrays!

       Rows   x   Columns on PhotoPeach


Which array is your favorite?

Do you know more factors that will make square arrays?

Do you see any arrays in your home?

Tell us about it in your comments!

  1. Dear Mrs. Ranney and Frogger,

    I know the answer to your question, it is 9 rows of 10=90, so 10x9=90.

    I know the answer to Alex's array, it is 3 rows of 4=12, so 3x4=12.

    Cheers,

  2. Dear Mrs. Ranney,

    The answer to Frogger`s problem is 10 rows of 9. Another square array is 7x7=49 because the factors are the same. I see an array of two rows of three. So many arrays are here but I had to choose only one so I chose that one.

    Sincerly,

    1. Dear Jackson,

      You did a wonderful job of using html code!
      What is the product in Frogger's problem?

      I'd love to hear more about the array you found at home. What was in the two rows of three?

      Cheers!

  3. Dear Mrs. Ranney,

    My favorite array is Alex's array beacuse I love donuts. My favorite flavor is chocolate glazed.Sometimes on a special Sunday, my mom takes me to Blinkies donuts.

    Two factors that will make a square array are nine and nine.

    I used to have an array of sea shells in my room.

    Best Wishes,

    1. Dear Tyler,

      What a great job you did of using html code!

      I have a couple of questions:
      What is the product in the 9 x 9 array?
      What array were your sea shells in? How many shells were there?

      Cheers!
      Mrs. Ranney

    2. Dear Mrs. Ranney,

      The product in the 9 x 9 array is 81. I don't remember how many shells were in my array because my nanny moved it.

      Cheers,

  5. Dear Alexandra,

    I thought your headband array was very interesting.
    One thing I really enjoyed about your array was that all of your headbands have a different design on them.
    I really loved your array.


    Best Wishes,

  6. Dear Ms. Ranney.

    My favorite posted array was Alex's doughnuts. I love it because they are delicious. The yummiest part are the sprinkles.

    My own array is my Wii game Collection.. not as yummy!!

    Sincerely,

    Shai

  8. Hello Mrs. Ranney and class,

    I think all of these arrays are amazing. I particularly liked the tasty looking cupcake array but I don't think I'd be able to make one like it because I don't think I'd be able to stop making cupcakes disappear.

    DO I see any arrays in my home?

    I use arrays quite often. In my case, they're more likely to be on computer spreadsheets where I have to set up columns and rows of information.

    I also see them in tile patterns and books on shelves. I can count rows and then the columns to work out how many. Here's an example...

    In an ensuite bathroom, there are 10 rows and 7 columns or large tiles. I know there are 70 tiles without having to count each tile. That's much easier.

    Keep sharing your learning adventures. :)

  9. Dear Mrs. Ranney and Class,

    I love all the amazing arrays!!! I like Alexander's in particular. I think it was very clever to come up with headbands for her array.

    I think the arrays with the name tags, toys, and markers are the most colorful!!! I also watched the video on rows and columns and found it very interesting!!! It helped me understand a lot better then I even did before!!! I thought I had it down before, but now I'm even better at it!

    Now, I have some questions to ask you:

    Which array was your favorite?
    What array do you find the most colorful?
    Do you think the video helped you understand better?
    Do you know array's even better now?

    Those are some questions I wanted to ask you.

    I like answering questions, so I ask you a lot of them so if you like them like I do, then you get a chance to answer some.

    At my house, I have a lot of rows of food in my cuboard!!! They're all in nice and neat rows on the shelves.

    In the front yard of my house, I have rows of rocks. They're all pretty, small stones laid out on the grass. I like to look at them somtimes. I think in my head, oh, I never noticed there was 6 rows and 4 columns!!! Even though I'm not at school, I still see a lot of arrays everywhere I go!!!!!

    Warmly,
    Miranda ( from Canada)!!!

    Dear Miranda,

    Thank you for visiting our blog. :) You asked many interesting questions my favorite array is Alex's cupcake array because I adore cupcakes. My partner thinks that Alexandra's array is very colorful!

    Yes, the video helped us understand more because it's a quiz, and quizzes are helpful. Yes I know arrays better now .


    Cheers,

    Matthew and Christopher
