"Good morning, class! Today, we are going to explore an exciting topic in mathematics: triple-digit subtraction! This is important because it helps us with all sorts of real-life situations, like budgeting or calculating scores. Our goals for today are to understand how to subtract triple-digit numbers, to work well together in groups, and to have some fun while we learn! Let’s get started!"
"First, let’s review what subtraction is. Can anyone tell me what subtraction means? (Pause for responses.) Great! It’s taking one number away from another. Now, when we deal with triple-digit numbers, it's a bit more complex. Let’s look at an example on the board together. (Write an example, such as 324 - 198.)
As we can see, there are three digits to consider, and sometimes we need to regroup. Who can remind me what regrouping is? (Pause for responses.) Exactly! If we don’t have enough to subtract from a digit, we have to borrow from the next digit.
Now, let’s practice a few examples together! (Provide another example and work through it as a class.)"
"Now it’s time for some group work! I’m going to divide you into groups of four. Each group will receive a worksheet with some triple-digit subtraction problems. I want you to work together and solve these problems. Remember, communication is key! You can ask each other questions and discuss the best ways to approach each subtraction problem. I will give you 7 minutes for this. Let’s get started!"
"Okay, everyone! Let’s take a quick break to refresh our minds and bodies. Stand up and stretch your arms high towards the ceiling! Now, let’s do a quick game. I’ll say a number, and you can’t sit down until you give me that number of jumping jacks. Ready? 5 jumping jacks! Go! (Lead the activity.) Great job, everyone! Now, let's sit back down and get back to our lesson."
"I’m going to hand out some printable cards to each of you. On these cards, I want you to write down one important thing you learned today about triple-digit subtraction. It could be about the process, how to regroup, or even something you found interesting during the group activity. Take about 5 minutes to fill these out."
"Now, I’d like everyone to pass their cards to the front of the class. I’ll take a moment to look through them to understand how well you grasped the topic today. I won’t be calling anyone out; this is just to help me see where we are with our learning. Thank you for your participation!"
"For your homework, I would like you to practice triple-digit subtraction. I will provide you with a worksheet, and I want you to complete it by our next class. Please remember to read the instructions carefully! Practicing at home will help you feel more confident with this topic. Does anyone have any questions about the homework?"
"To wrap up today’s lesson, let’s quickly review what we’ve learned! We talked about the concept of triple-digit subtraction and practiced it together in groups. I’m proud of how you all worked together! Remember, if you have any questions, feel free to ask me anytime. Don’t forget about your homework! Keep practicing, and I look forward to seeing you all next time!"

What is the process of subtraction, and how is it applied to triple-digit numbers?
Explain what regrouping means in the context of triple-digit subtraction.
Solve the following problem: 482 - 276.
When subtracting, what do you do if the digit in the minuend is smaller than the digit in the subtrahend?
Create and solve your own example of a triple-digit subtraction problem.
How did group work help you to understand triple-digit subtraction better?
What is one key takeaway you learned about subtracting triple-digit numbers from today's lesson?
Give an example of a real-life situation where you might need to use triple-digit subtraction.
Using the numbers 753 and 248, perform the subtraction and show your work step by step.
Why is practicing subtraction at home important for your learning?
Subtraction is taking one number away from another; in triple-digit numbers, we need to consider all three digits, sometimes using regrouping.
Regrouping means borrowing from the next highest place value when the minuend’s digit is smaller than the subtrahend’s digit.
482 - 276 = 206.
If the digit in the minuend is smaller than the digit in the subtrahend, you regroup by borrowing from the next digit to the left.
(Example: 624 - 317 = 307; students should show their work.)
Group work allowed me to discuss and compare strategies with my classmates, which made the process clearer.
A key takeaway is that regrouping is essential when subtracting larger digits.
An example could be calculating expenses or keeping track of a budget.
753 - 248:
Practicing at home reinforces what we learned in class, builds confidence, and helps us master the topic.

# Let's Move and Groove!
Stand up tall, reach for the sky,
Touch your toes, let out a sigh.
March in place, knees high and proud,
Swing your arms, move with the crowd.
Five jumping jacks, quick as a bee,
Now spin around, feel the glee!
Shoulder rolls, back and forth,
Stretch your arms, give them worth.
Side-to-side, let's twist and bend,
Now leap like a frog, around the bend.
Take a deep breath, in and out,
Feel the energy, that's what it's about!
Wiggle your fingers, then stomp your feet,
Now sit back down, isn’t that sweet? Feel free to modify any part of it to better suit your class!
