"Good morning, everyone! Today, we are going to learn how to subtract double-digit numbers. Are you excited? I know I am!"
"Can anyone tell me what subtraction means? That’s right! Subtraction means taking away. When we subtract, we figure out how many are left after we take some away."
"First, let’s quickly review double-digit numbers. A double-digit number has two digits. For example, 23 has a 2 and a 3. The first digit represents the tens, and the second digit represents the ones."
"When we subtract double-digit numbers without regrouping, we’re taking away from the tens and the ones without needing to borrow. Let’s break it down with an example."
"Let’s solve the problem 34 - 12 together. We start with the bigger number, which is 34."
Subtract the ones: "We have 4 ones and we take away 2 ones. What’s 4 minus 2? That’s right, it’s 2."
Subtract the tens: "Now we look at the tens place. We have 3 tens and we take away 1 ten. What’s 3 minus 1? Great job, it’s 2!"
"So, if we put our answers together, 34 - 12 equals 22! You all did amazing!"
"Now it’s your turn to help me with another problem. Let’s try 45 - 21."
"Great! Let’s combine our answers. How much is 45 - 21? Excellent, it’s 24!"
"Let’s do a few more together. I will show you the problems on the whiteboard."
"Now, it’s time for you to try some problems on your own. I’m handing out a worksheet with 5 subtraction problems for you to complete. Remember to write your answers in the blanks after each problem. Don’t forget to check your work!"
"I’ll walk around the room to help you if you have any questions. Raise your hand if you need assistance."
"Let’s come back together as a class. Can anyone tell me what we learned today? Yes! We learned how to subtract double-digit numbers without regrouping!"
"You all did a fantastic job today! I’m so proud of you for learning something new."
"For homework, I’d like you to practice by solving five more subtraction problems from your math book. Be sure to show your work!"
"Thank you for your hard work today! I can’t wait to see you all back for our next lesson. Have a wonderful day!"
