Today we explored arrays!
Row x Column = Product
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 at the new shape!
Which square arrays are missing?
Do you see any arrays in your home?
Tell us about it in the comments!

Dear Mrs. Yollis' Class,
Wow! Looks like you have really explored arrays. I remember last year we did a post on arrays too.
It also looks hard to put a 12 by 12 square on whiteboards. But, it all looks great!

(P.S. Nice math skills.)
Dear Mrs. Yollis' Class,
I am always excited to see a new post from my favorite bloggers!
You did a fantastic job sharing your learning about arrays. I like the different patterns you made with the yellow and red pieces, that made the pictures even better.
My class will be learning arrays in a few weeks and I will be sure to share this post with them so they can learn from your great examples.
My keyboard has an array of buttons on the right side where the numbers are. The numbers are a 3x3 array, but with the buttons above them that are the same size it is a 4x3 array.
I look forward to your next post!

Dear Mrs. Yollis,
At home upstairs right by my stairs, I have an array in a cabinet. There are video games in the cabinet. The multiplication sentence is 23 X 2 = 46 video games. I also have an array on my guitar. The guitar strings. The multiplication sentence is 1 X 6 = 6 guitar strings.

Dear Mrs. Yollis,
I loved today in class making the arrays. It was so cool to learn about rows and columns.

Dear Mrs.Yollis,
I'm always excited to learn something new like multipication. I love multipication. Are we going to learn something like 11x11 this month?
Your student,
Kayla
Dear Mrs. Yollis,
I like the one that says 12x12=144. I thought that was so cool. It was really fun making arrays in the class and I wish I could do it every day. If you were in third grade and you were making arrays what mulpitcation sentence would you use.
Dear Mrs.Yollis,
I had fun making the 10 by 10 array. I was also amazed with the 12 by 12 array because it was huge.
Your friend,

Dear Mrs. Yollis' Class,
I love your arrays!
When I was a child, I don't remember using arrays to learn multplication facts. We just sat around memorizing the facts without a visual tool. It was incredibly boring and I would have benefited from learning the way you all are.
As I look around my house, I see square and rectangle shapes on the doors in a 2X3 array.
Warmly,
Kendall's mom
