| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

"Good morning, everyone! Today, we will be diving into an important topic in mathematics: rounding.
Now, why do we round numbers? Rounding helps us simplify numbers, making them easier to work with, especially when we need to make quick estimations in our daily lives, such as calculating costs or measuring distances.
We usually round numbers to the nearest ten, hundred, or thousand, and there are specific rules that we will go through today. How many of you have had to round numbers in real-life situations before? Great! Let’s talk about the rules of rounding.
When we round a number, we look at the digit to the right of the place we are rounding to. If that digit is 5 or higher, we round up. If it’s 4 or lower, we round down. Remember, rounding helps make numbers easier to work with, and today, we’re going to master it together!"
"Now, I'm going to hand out these printable rounding cards to each of you. Please take one and pass them around until everyone has one.
Each card has spaces for you to write down different numbers and the rounded results. Let's go through an example together.
If I have the number 67, what would you say is the nearest ten? Yes, that’s right! It’s 70 because we look at the 7 in the units place and since the next number is 5 or higher, we round up.
Now, please write down the number 67 on your card, the nearest ten as 70, and just follow along as we do more examples together.
Take your time to fill in the card following my examples.”
"Let’s practice together. I will write some numbers on the board, and I want you to tell me how to round them. First up, we have 234.
What’s the nearest hundred? Correct, it’s 200! Now, what about 845? Yes, that’s right; the nearest hundred is 800.
Let’s do one more: How about 1,459? Yes, it rounds to 1,500! Really great job, everyone!
This practice is important because rounding is a skill you will use often, not just in maths class but in your everyday lives as well."
"Now, I’m giving you some time to work independently on your rounding cards. Use what we've just discussed to fill out your cards with different numbers.
Remember to think about which digit you are rounding to and apply the rules we talked about. I’ll be walking around the room, so if you have any questions or need help, please feel free to ask."
"Alright, everyone, time's up! Now, I would like to randomly collect a few rounding cards. This is just to check how well we’ve understood the concepts today.
I’ll look through a few of them and provide feedback quickly. This isn’t a formal assessment, so don’t worry. I just want to see how you’re getting on with rounding.
If you have made any mistakes, it’s a good opportunity to learn from them!"
"Finally, for your homework, I want you to complete the rounding task I will hand out shortly. You will find various numbers to round, and I would like you to complete this at home.
You will need to bring it in next lesson to be submitted, but there will be no presentations, so just focus on doing the work right.
Does anyone have any questions about the homework or what we covered today? Excellent! Thank you for your participation today; I’m proud of your efforts!"
Round the following numbers to the nearest ten:
Round the following numbers to the nearest hundred:
Round the following numbers to the nearest thousand:
For each of the following scenarios, write down the number and what it would round to the nearest ten:
Explain the rounding rules in your own words. What do you do if the digit to the right is 5 or higher? What if it is 4 or lower?
Complete the following table by rounding the numbers provided to the nearest ten, hundred, and thousand:
| Number | Nearest Ten | Nearest Hundred | Nearest Thousand |
|---|---|---|---|
| 154 | |||
| 879 | |||
| 3,456 | |||
| 76 |
Create a real-life example where rounding is useful. Explain the situation and the numbers involved, rounding as necessary.
