Adding numbers can be super fun, especially when you’re building towers of LEGO bricks or counting your favorite candies! But sometimes, when we add bigger numbers, we need a little extra help to keep everything organized. That’s where “regrouping” comes in it’s like a secret trick to make addition even easier!
Think of regrouping as moving pieces from one column to another when things get too crowded. It’s like when you have too many toys in one box, and you need to move some to another box to make everything fit nicely. Ready to learn more about this cool trick? Let’s dive in!
Mastering 3 Digit Addition with Regrouping
Let’s start with an example: 247 + 185. First, we line up the numbers vertically, making sure the ones, tens, and hundreds places are all in their own columns. This helps us keep track of what we’re adding together. Neatness counts! Get those digits in a row.
Now, let’s look at the ones column: 7 + 5 = 12. Since 12 is more than 9, we can’t write it all in the ones column. We write down the “2” in the ones place and “regroup” the “10” (from the 12) by carrying the “1” over to the tens column. It’s like giving that extra ten a new home!
Next, we move to the tens column. We have 4 + 8 + 1 (the one we carried over). That equals 13. Again, 13 is more than 9, so we write down the “3” in the tens place and carry the “1” over to the hundreds column. Are you starting to get the hang of it?
Finally, we add the hundreds column: 2 + 1 + 1 (the one we carried over) = 4. So, we write “4” in the hundreds place. Putting it all together, 247 + 185 = 432! You just solved a 3-digit addition problem with regrouping!
Practice makes perfect! Try different problems, and don’t be afraid to make mistakes. Regrouping might seem tricky at first, but with a little practice, it will become second nature. Soon you will be able to tackle any addition problem that comes your way with confidence and ease.
Now that you’re a 3-digit addition with regrouping whiz, why not put your skills to the test? Find some more practice problems online or in a math workbook. The more you practice, the better you’ll become. Get ready to become an addition master! Enjoy the journey and happy adding!
