Today, we’re going to learn a fun way to add numbers by breaking them into smaller parts. This will help you understand how to add big numbers easily!
First, we need to break down the numbers into smaller parts. We call this “partitioning.” Let’s say we have the numbers 43 and 25. We can split them into tens and units like this:
Now, let’s put the tens together and the units together. This means we will add the tens and then the units separately:
Next, we add the numbers in each group:
Finally, we combine the sums to find the total:
60 + 8 = 68
So, 43 plus 25 equals 68!
Try practicing this method with different numbers. You can start by writing them down and then try doing it in your head. It’s like a puzzle, and the more you practice, the better you’ll get!
Remember, breaking down numbers makes adding them much easier and more fun. Happy adding!
Number Hunt: Go on a number hunt around your house or classroom. Find two numbers that you can add together. Break them down into tens and units just like we learned. Write them down and use the partitioning method to add them. Share your findings with a friend or family member and explain how you got your answer!
Build with Blocks: Use building blocks or LEGO pieces to represent tens and units. For example, use one color for tens and another color for units. Pick two numbers to add, and build towers for each number using the blocks. Break them into tens and units, then combine the towers to find the total. This hands-on activity will help you visualize the addition process.
Story Time Addition: Create a short story where two characters find treasures. Each treasure has a number on it. Break down the numbers into tens and units, and use the partitioning method to add them together. Draw a picture of your story and write the math problem you solved. Share your story with the class or your family!

In this video, we will go through the steps of partitioning numbers to help you gain a secure understanding of the process.
**Step 1: Partitioning Numbers**
Start by segmenting or partitioning the numbers into tens and units. For larger numbers, you can also break them down into thousands, hundreds, tens, and units. For example, you can partition the number into 40 plus 3 plus 20 plus 5.
**Step 2: Grouping Like Terms**
Next, place the tens and units together, matching like for like. For instance, 40 plus 20 are the tens, and 3 plus 5 are the units.
**Step 3: Calculate and Recombine**
Once you have grouped the numbers, calculate their sums. In this case, 40 plus 20 equals 60, and 3 plus 5 equals 8. Then, recombine these results to get your final answer, which is 68.
Make sure to discuss these steps with your child to ensure they have a solid understanding of each part of the process. You can start with written exercises and then progress to mental strategies. This is a popular method used in my classroom.
