Hello, friends! Today, we’re going to have some fun with numbers using base 10 blocks. These blocks help us understand how to add numbers easily. Let’s get started!
Base 10 blocks are special blocks that help us count. There are two types of blocks:
Now, let’s use these blocks to add numbers. We’ll look at some examples together.
First, let’s count the cubes (ones). On one side, we see three cubes, and on the other side, we see four cubes. If we add them together, we get seven cubes or seven ones.
Next, let’s count the longs (tens). On one side, there are two longs, and on the other side, there is one long. Counting by tens, we have ten, twenty, thirty. So, we have three tens.
So, in total, we have three tens and seven ones. That’s the correct answer!
Let’s try another one. Count the cubes first. On one side, there’s one cube, and on the other side, there are five cubes. Together, they make six ones.
Now, count the longs. On one side, there are five longs. So, we have five tens and six ones. That’s our answer!
For the last example, let’s count the cubes again. On one side, there are nine cubes, which means we have nine ones.
Now, let’s count the longs. There’s one long on one side and five longs on the other side. That makes six tens in total.
So, we have six tens and nine ones. Great job!
Cubes are for counting ones, and longs are for counting tens. Keep practicing, and you’ll become a math superstar!
Thanks for learning with us today. See you next time for more fun with numbers!
Build Your Own Numbers: Use small objects like buttons or coins to represent cubes (ones) and straws or sticks to represent longs (tens). Try creating different numbers by combining these objects. For example, make the number 23 by using two straws and three buttons. Can you make the number 45? How about 67?
Number Hunt: Go on a number hunt around your house or classroom. Look for numbers in books, on clocks, or even on food packages. Try to represent these numbers using your base 10 blocks or the objects you used in the first activity. How many tens and ones do you need for each number you find?
Story Time with Numbers: Create a short story using numbers and base 10 blocks. For example, “Once upon a time, there were three longs and five cubes living in a magical land. One day, they met two more longs and four more cubes. How many longs and cubes are there now?” Share your story with a friend or family member and solve the number puzzle together!

Welcome to Kids Academy! Hello everyone! Let’s open the worksheet. Don’t forget to like this video and subscribe to our channel. You can find the link to this app in the comments below.
Today, we’re going to be using base 10 blocks to add. Let’s remind ourselves what each of the base 10 blocks represents. A cube represents one individual number. For example, if I had four cubes, that equals four.
The other base 10 block we’re going to look at is called a long or ten. A long is made up of ten individual cubes, so a long or ten equals ten. If I had three longs or three tens, that would be equal to thirty. We can count by tens when we’re adding these up: ten, twenty, thirty.
Let’s use this information to help us complete the worksheet. Let’s read the directions and get started right away. Count longs and cubes in each number sentence. How many tens and ones are there in total? Check the correct answer.
When we’re counting tens and ones, I always like to start with the ones because when we’re adding, we usually start with the place furthest to the right. So first, let’s count the individual cubes.
On the first side of the equation, I see three cubes. On the right side of the equation, I see four cubes. If I want to count them up in total, I could add three plus four, or I could just count the cubes altogether to find the total.
Counting in total, I have seven cubes or seven ones. Now let’s count the tens. On the left side of the equation, I see two tens. On the right side of the equation, I see one ten. We can count by tens to find out the total: ten, twenty, thirty. That shows me that there are three tens.
We could add 20 (represented by these two tens) plus 10 (represented by this one ten) to give us a total of 30. We already know that there are seven ones, so let’s count the tens to find out how many there are. I see three tens and seven ones. The first answer choice is correct.
Let’s take a look at the next example. Let’s start by counting the ones in the second example. On the left side of the equation, I see one cube. On the right side of the equation, I see five cubes. That gives us a total of five ones.
Now let’s count the tens. On the left side, I see five tens. So now I’m left with five tens and five ones, which is our third answer choice.
In our final example, we’re going to start by counting the ones again. Let’s count them all together. On the left side of the equation, I see nine cubes, which means I count nine ones in total.
Now let’s continue by counting the tens. I have one ten on the left side and five tens on the right side. That gives us a total of five tens and nine ones.
Remember, the cubes represent ones, and the longs or tens represent ten cubes altogether. Thanks for watching, and we’ll see you next time!
