### Annotated Arrays!

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 is a square!

Let's look for arrays!

We walked around the school looking for arrays. Once we captured our arrays on our iPads, we went back to class and used Skitch to annotate our images. Here is the definition of annotate!

Images +  = great illustrations!

Wow!

Which array did you photograph and annotate?

What are some tips you can share about using Skitch   to annotate?

1. Dear Mrs. Yollis an class,

One thing I have noticed about patterns (including arrays) is how many places we can find them when we know what to find. I can see you found many examples but when I read the word "array" something else came to mind.

Have you heard of solar arrays?

This is a term used to describe sets of solar panels. Perhaps you have them on the school roof. They are found in many places, even in space. Here is a NASA link showing arrays in space...

Looking at my computer keyboard, I see it also has an array for the numeric keypad. My phone has an array for the buttons. My calendar has an array of boxes for the dates...

Suddenly I'm seeing arrays in a number of places. :)

2. We will be learning about arrays next week so we are pleased to have found your post. It told us a lot about what we will be learning about.

Thanks,
