Hello, everyone! Today, we’re going to learn something fun with Teacher Mike from Kids Academy. We’re going to talk about arrays. Are you ready? Let’s go!
An array is a group of things like objects, pictures, or numbers that are arranged in rows and columns. Imagine a rectangle filled with neat rows and columns. That’s what we call a rectangular array!
Let’s say we have pictures of cats. If we have three cats in the first row, we should also have three cats in the second row, three in the third row, and three in the fourth row. We can have as many rows as we want, as long as there are three cats in each row. This is how we make an array!
To find out how many cats there are in total, we just count them all: one, two, three, four, five, six, seven, eight, nine, ten, eleven, and twelve. Arrays make counting easy and help us learn multiplication later on!
Let’s look at some pictures to find arrays. Our job is to check if they show rectangular arrays.
The first picture shows stars in a circle. Since arrays need rows and columns, and this picture doesn’t have them, it’s not an array.
The second picture has houses. There are four houses in the first row and four in the second row. There are also two houses in each column. This is a rectangular array!
The third picture has smiley faces. The first row has four smiley faces, but the second row has only two. For it to be an array, each row should have the same number, so this isn’t an array.
The next picture shows snails. There are three snails in each row and three in each column. This is a perfect rectangular array!
This picture looks like a square or rectangle, but it’s blank in the middle. The first row has five, but the second row has only two. So, this is not an array.
The last picture shows beach balls. There are five in each row and four in each column. Since all rows and columns have equal numbers, this is an array!
When you’re checking if something is an array, make sure it has the same number in each row and column. Arrays help us organize and count things easily!
Thanks for learning with us today! Don’t forget to check out more fun videos and activities. See you next time!
Array Hunt at Home: Look around your house and find objects that can be arranged into arrays. You might use toys, blocks, or even snacks like crackers. Arrange them into rows and columns. Ask yourself: “Does each row have the same number of items? Does each column have the same number?” Share your array with a family member and explain why it is an array.
Draw Your Own Arrays: Take a piece of paper and draw different arrays using shapes like circles, squares, or stars. Try making an array with 3 rows and 4 columns, and another with 2 rows and 5 columns. Count how many shapes are in each array. How many shapes are there in total? Can you create a new array with the same total number of shapes but a different arrangement?
Array Story Time: Create a short story or comic strip about a character who loves organizing things into arrays. Maybe they organize their toys, books, or even fruits. Draw pictures to show how they arrange these items into rows and columns. Share your story with a friend or family member and ask them to find the arrays in your drawings.
Sure! Here’s a sanitized version of the transcript:

Welcome to Kids Academy! Hello, boys and girls! This is Teacher Mike with Kids Academy, and today I’d like to teach you about arrays. But before we get to today’s worksheet, let’s talk about what an array really is.
An array is just a group of objects, pictures, and numbers that are arranged in rows and columns. A rectangular array is an array that is arranged in equal columns and rows, and it takes the shape of a rectangle.
For example, if we had pictures of cats and we had three cats in the first row, that would mean we would also have three cats in the second row, three in the third row, and three in the fourth row. We can make as many rows as we want, as long as there are three in each row, because that’s how we’ve created our array.
To find out how many there are in total, we can just count all of our cats. Let’s count them up: one, two, three, four, five, six, seven, eight, nine, ten, eleven, and twelve. Putting objects in arrays makes them easy to count and will also help with multiplication later on.
Now, let’s read the directions for our worksheet and get started right away.
**What’s an array?** Check all the pictures that show rectangular arrays.
In our first picture, I see a circular group of stars. I know that it has to have columns and rows, and I don’t see any columns and rows in this picture, so this is not an array.
Our second picture shows houses. In this picture, there are four houses in the first row and four houses in the second row too. We have to make sure there’s an equal number in each row and in each column. I can clearly see that there are four in each row and two in each column, so this shows me that this is an array.
Let’s look at our next picture of smiley faces. In this picture, there is not an equal number in each row. In our first row, there are four smiley faces, and in our second row, there are only two. For this to be an array, there would have to be four smiley faces in each row, and there’s not, so this isn’t an array.
Now, let’s move on to the next picture. In this picture, I see snails. In the first row, there are three, in the second row, there are three, and in the third row, there are three. This looks nice and even, but let’s count the snails in the columns just to be sure. There are three in the first column, three in the second column, and three in the third column. This is definitely a rectangular array, so let’s check this one.
Let’s look at our next picture. Although this picture does look like a square or a rectangle, it is completely blank in the middle. If we were to count the number in the first row, there are five, but in the second row, there are just two. So this is not an array.
Finally, if we look at our last picture of beach balls, this does look like a rectangular array as well. In the first row, there are five, and if we look closely in all the other rows, there are also five beach balls. That’s a good start!
Now, let’s count the numbers in the columns just to be sure. In the first column, there are four, and in all the other columns, there are also four. Since the columns and rows all contain equal numbers, this is an array.
Remember, boys and girls, when you’re looking to see if an object is an array or not, make sure it has an equal number in each row and an equal number in each column.
