Decimals to the Hundredth and Rounding Decimals
Grade 5-6 (Ages 10-12)
Mathematics
26 Students
40 minutes
This lesson aligns with the Australian Curriculum: Mathematics, particularly in the Number and Algebra strand.
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction | 5 mins | Briefly discuss the importance of decimals in real life. Introduce the concept of hundredths. Use examples. |
| 2 | Direct Instruction | 10 mins | Explain how to read, write, and compare decimals. Introduce the decimal place value chart and number line. Showcase examples of rounding to the nearest whole number and tenth. |
| 3 | Guided Practice | 10 mins | Distribute worksheets. Work through a few examples as a class. Encourage group discussions. Monitor and assist. |
| 4 | Independent Practice | 10 mins | Students complete the remainder of the worksheet individually. Circulate to provide help where needed. |
| 5 | Review and Assess | 5 mins | Briefly go over the answers to the worksheet. Use a rounding quiz for assessment. Provide solutions for self-checking. |
| 6 | Homework Assignment | 5 mins | Assign homework on rounding decimals. Explain that it should be completed independently and will be checked without presentations in class. |
"Good morning, class! Today, we will be diving into an important topic in mathematics: decimals to the hundredth and rounding decimals. Can anyone tell me where we might use decimals in everyday life?
[Pause for responses]
"Great answers! Decimals are used in money, measurements, and even in sports scores. Today, we will focus on understanding decimals up to the hundredths place and how to round them. By the end of the lesson, you will be able to use rounding in real-life scenarios. Let’s get started!"
"First, let’s take a closer look at what we mean by decimals. On the whiteboard, I’m drawing a decimal place value chart."
[Draw a decimal place value chart on the whiteboard]
"Here, you can see the place values: tenths, hundredths, and so on. For example, in the number 0.75, 7 is in the tenths place and 5 is in the hundredths place.
"Now, let’s talk about how to round decimals. First, we will round to the nearest whole number. Look at this number: 4.6. To round it, we look at the digit in the tenths place. Since 6 is greater than or equal to 5, we round up to 5. So, 4.6 rounded to the nearest whole number is 5.
"Next, let’s round to the nearest tenth. Consider the number 2.34. The digit in the tenths place is 3, and the hundredths place is 4. Since 4 is less than 5, we don’t round up, and 2.34 rounded to the nearest tenth is 2.3.
"Does everyone understand how the decimal place values work and how we round?"
"Now it’s your turn! I’m handing out worksheets with some decimal problems. Let’s solve the first one together.
[Distributing worksheets]
"Look at the first question: round 5.78 to the nearest whole number. What do we look at? Yes, the tenths place, which is 7. Since 7 is greater than 5, we round up!
"Let’s do another one together—round 3.21 to the nearest tenth. Who can tell me what to do?
[Encourage responses, guiding them through]
"Great job! Now, I want you to work with a partner and discuss the remaining problems on the worksheet. I’ll be walking around to assist you if you have any questions."
"Alright, everyone! Now it’s time for you to work on the rest of the problems individually. Please complete the worksheet independently.
[Circulate the room, offering help where needed]
"If you have any questions or need help, just raise your hand. Remember, rounding is a useful skill, so take your time and do your best!"
"Time is up! Let’s go over the answers together. For the first few problems, I’ll write them on the whiteboard, and you can check your answers on your worksheets.
[Go through the answers, encouraging questions]
"Now, I have a quick rounding quiz for you to assess your understanding. It will have a few questions similar to what we’ve just practiced. You have 3 minutes to complete it!"
[Administer the quiz]
"Make sure to check your answers when you’re done!"
"For homework, I’d like you to complete a worksheet on rounding decimals.
[Distribute the homework assignment]
"Remember, it’s important to do your best on this independently, as I will check it for completion. There is no need for presentations in class; I just want to see that you understand the concept.
"Do you have any questions about the homework? Great! Don’t forget to bring it back for our next class."
