Hello friends! Today, we’re going to learn about subtraction with a fun worksheet called “Christmas Cookies Subtraction.” Let’s dive in and see how we can solve these problems using a special trick called regrouping.
Regrouping is like borrowing from your neighbor when you need more. In subtraction, if the top number is smaller than the bottom number, we borrow from the next door number to help us out. Let’s see how it works with some examples!
Look at the number 321. We want to subtract 17 from it. But wait! The number 1 is smaller than 7, so we can’t take 7 away from 1. What do we do? We borrow from the tens place!
The number 2 in the tens place is actually 20. If we take 10 from it, it becomes 10. Now, we add that 10 to the 1, making it 11. Now we can subtract 7 from 11. Let’s count: 7, 8, 9, 10, 11. That’s 4! So, 11 minus 7 is 4.
Next, we subtract the tens and hundreds: 1 minus 1 is 0, and 3 minus nothing is 3. Our answer is 304!
Let’s try another one: 956 minus 37. Again, the 6 is smaller than 7. Time to borrow! We take 10 from the 5 in the tens place, turning it into 4. Now, the 6 becomes 16.
Subtract 7 from 16, which is 9. Then, 4 minus 3 is 1, and 9 minus nothing is 9. Our answer is 919!
Now, let’s do 472 minus 14. The 2 is smaller than 4, so we borrow from the 7 in the tens place, making it 6. The 2 becomes 12.
Subtract 4 from 12, which is 8. Then, 6 minus 1 is 5, and 4 minus nothing is 4. Our answer is 458!
Next, we have 860 minus 35. The 0 can’t give anything, so we borrow from the 6 in the tens place, turning it into 5. The 0 becomes 10.
Subtract 5 from 10, which is 5. Then, 5 minus 3 is 2, and 8 minus nothing is 8. Our answer is 825!
Finally, let’s solve 592 minus 76. The 2 is smaller than 6, so we borrow from the 9 in the tens place, making it 8. The 2 becomes 12.
Subtract 6 from 12, which is 6. Then, 8 minus 7 is 1, and 5 minus nothing is 5. Our answer is 516!
If the top number is smaller than the bottom number, borrow from the next place. You’re borrowing 10 from the tens place to help the ones place. It’s like getting help from a friend!
Thanks for learning with us! Keep practicing, and you’ll be a subtraction superstar in no time!
Subtraction Scavenger Hunt: Create a subtraction scavenger hunt at home! Ask an adult to hide small objects like toys or candies around the house. Use subtraction to find out how many are left after you find some. For example, if there are 10 candies and you find 3, how many are left? Practice regrouping if needed!
Regrouping Role Play: Pretend you are a shopkeeper. Use play money or paper cutouts to practice subtraction with regrouping. If a customer buys something and you need to give change, use regrouping to figure out how much change to give. For example, if an item costs 15 and the customer gives you 20, how much change do you give back?
Observation Challenge: Look around your home or classroom and find examples of subtraction in action. Can you see someone using subtraction when cooking, shopping, or playing games? Write down or draw what you see and explain how regrouping might help in those situations.
Sure! Here’s a sanitized version of the transcript:

Today, we’re going to be looking at a worksheet called “Christmas Cookies Subtraction.” Let’s read the directions and look at an example so that we’re ready to solve the problems on this worksheet.
We will subtract using regrouping in each row and circle the correct total. Let’s look at an example before we get started.
For example, the number 321 minus 17. In this problem, you’ll see that the top number in the ones place is smaller than the bottom number in the ones place. You can’t take away seven from one because one only has one to give. So, we’re going to have to borrow from the tens place. The two in the tens place really represents twenty. When we take one away, it becomes ten. The ten that we’re taking away will help us with the one in the ones place. Ten plus one is eleven, so the one becomes eleven.
Now you can take away seven from eleven because eleven has seven to give. Let’s count upwards from seven to eleven to see the difference between those two numbers: seven, eight, nine, ten, eleven. Eleven minus seven is four.
Now we can just move along and continue subtracting. One minus one is zero, and three minus nothing is three, giving us an answer of 304.
Let’s use this strategy of regrouping to help us solve the rest of the problems.
Our first problem is 956 minus 37. We have the same situation as we had in the example. The top number in the ones place is smaller than the bottom number in the ones place, so we’re going to look next door to the tens place and borrow a ten from five. Five will become four, and that ten we borrowed will add to six, making it sixteen.
Now, sixteen minus seven is nine. Just like before, we continue subtracting from right to left. Four minus three in the tens place leaves us with one, and nine minus nothing in the hundreds place is nine, giving us a difference of 919. Let’s go ahead and circle that.
Our second problem is 472 minus 14. Again, the top number is smaller than the bottom number. You cannot take away four from two, so we must borrow from the tens place. If we cross out seven in the tens place, it turns into six. The ten we borrowed will be added to the two, making it twelve.
Twelve minus four gives us eight in the ones place. Six minus one is five, and four minus nothing is four, giving us a total difference of 458.
Our third example is 860 minus 35. In the ones place, there’s a zero, which has nothing to give, so we’re going to have to borrow from the tens place. We can borrow ten from sixty and turn our sixty into fifty, giving that ten to the ones place.
Now we have ten minus five, which is five. Subtracting from right to left, five minus three is two, and eight minus nothing is eight, giving us a difference of 825.
Finally, we have 592 minus 76. Again, the top ones place number is smaller than the bottom ones place number, so we’re going to have to borrow from the tens place. Let’s take away one ten from nine, which represents ninety, and turn it into eight, which now represents eighty.
We’ll take that ten and give it to the two in the ones place, making it twelve. Twelve minus six is six. Continuing to subtract from right to left, eight minus seven is one, and five minus nothing is five, leaving us with a total difference of 516.
Remember, if the top number is smaller than the bottom number, whether in the ones place or the tens place, you have to borrow from the place next door. You’re borrowing the value of that digit, so if you borrow one from the tens place, you’re really borrowing ten to add to the previous place.
