Rounding Numbers Up to 10,000 - Grade 3-4 Math Worksheet

Let’s solve the rounding problems step by step.

---

First Worksheet: Front End Rounding 3

Front end rounding means we round based on the first digit (the leftmost digit) and change all other digits to zero. But if the next digit is 5 or more, we round up the first digit.

Let’s go number by number:

1. 5766 → First digit is 5. Next digit is 7 (≥5), so round up → 6000
2. 6913 → First digit 6, next is 9 (≥5) → 7000
3. 8046 → First digit 8, next is 0 (<5) → 8000
4. 4752 → First digit 4, next is 7 (≥5) → 5000
5. 1765 → First digit 1, next is 7 (≥5) → 2000
6. 2398 → First digit 2, next is 3 (<5) → 2000
7. 7125 → First digit 7, next is 1 (<5) → 7000
8. 3587 → First digit 3, next is 5 (≥5) → 4000
9. 5578 → First digit 5, next is 5 (≥5) → 6000

✔ All front end rounded answers for Worksheet 1:
- 5766 → 6000
- 6913 → 7000
- 8046 → 8000
- 4752 → 5000
- 1765 → 2000
- 2398 → 2000
- 7125 → 7000
- 3587 → 4000
- 5578 → 6000

Second Worksheet: Checking the Rounding 2

Part A: Circle the student’s mistakes and write correct answer.

We are told to round to the bold, underlined digit. Let’s check each row.

Row 1:
Original: 9681 → bold is 9 (thousands place). So round to nearest thousand.
Student wrote: 9700 → ✘ Wrong! Should be 10000 (because 9681 is closer to 10000 than 9000? Wait — actually, 9681 rounds to 10000 when rounding to thousands? Let’s think:
Rounding 9681 to nearest thousand: look at hundreds digit = 6 ≥5 → round up 9→10 → so yes, 10000

But wait — maybe they meant rounding to the bold digit’s place value? The instruction says “round these numbers to the bold, underlined digit.” That usually means round to that place.

So:

1. 9681 → round to thousands → 9681 → hundreds digit is 6 → round up → 10000
Student said 9700 → wrong → Correct: 10000

2. 5920 → round to thousands → 5920 → hundreds=9 → round up → 6000
Student said 6000 → ✔ Correct

3. 1627 → round to thousands → 1627 → hundreds=6 → round up → 2000
Student said 1670 → ✘ Wrong → Correct: 2000

4. 6508 → round to thousands → 6508 → hundreds=5 → round up → 7000
Student said 7000 → ✔ Correct

Now right column:

5. 2643 → round to thousands → 2643 → hundreds=6 → round up → 3000
Student said 2600 → ✘ Wrong → Correct: 3000

6. 2667 → round to thousands → 2667 → hundreds=6 → round up → 3000
Student said 8000 → ✘ Way off → Correct: 3000

Wait — that can’t be right. 2667 rounded to thousands is 3000, not 8000. Maybe typo? Or misread? Anyway, per math: 2667 → 3000.

7. 3978 → round to thousands → 3978 → hundreds=9 → round up → 4000
Student said 3000 → ✘ Wrong → Correct: 4000

8. 8334 → round to thousands → 8334 → hundreds=3 → round down → 8000
Student said 8100 → ✘ Wrong → Correct: 8000

Wait — let me double-check the original image text. In the user’s image description, it says:

> Round these numbers to the bold, underlined digit.

And lists:

Left column:
- 9681 → 9700
- 5920 → 6000
- 1627 → 1670
- 6508 → 7000

Right column:
- 2643 → 2600
- 2667 → 8000 ← this must be a mistake in the problem or student error
- 3978 → 3000
- 8334 → 8100

Actually, looking again — perhaps the bold digit indicates which place to round to. For example, in “2643”, if the ‘2’ is bold, we round to thousands. But if the ‘6’ were bold, we’d round to hundreds. But in the text provided, only the first digit is shown as bold in the list.

Wait — in the original problem statement from the image, it says:

“Round these numbers to the bold, underlined digit.”

In the table, for example:

First row: “9681” with 9 bold → round to thousands → 10000

But student wrote 9700 — which is rounding to hundreds? That doesn’t match.

Perhaps there’s confusion. Let me re-read the instructions carefully.

Actually, in many such worksheets, “round to the bold digit” means round to the place value of that digit.

So:

- If 9 is bold in 9681 → round to thousands → 10000
- If 5 is bold in 5920 → round to thousands → 6000
- If 1 is bold in 1627 → round to thousands → 2000
- If 6 is bold in 6508 → round to thousands → 7000

Same for right side:

- 2 bold in 2643 → round to thousands → 3000
- 2 bold in 2667 → round to thousands → 3000 (student wrote 8000 — big mistake)
- 3 bold in 3978 → round to thousands → 4000
- 8 bold in 8334 → round to thousands → 8000

So corrections:

Mistakes are in rows where student answer ≠ correct rounding to the bold digit’s place.

Correct answers for Part A:

1. 9681 → should be 10000 (not 9700)
2. 5920 → 6000 ✔
3. 1627 → 2000 (not 1670)
4. 6508 → 7000 ✔
5. 2643 → 3000 (not 2600)
6. 2667 → 3000 (not 8000)
7. 3978 → 4000 (not 3000)
8. 8334 → 8000 (not 8100)

So circle mistakes in rows 1,3,5,6,7,8.

Part B: Round using front end rounding.

Numbers given:

- 5431 → front end: first digit 5, next is 4 <5 → 5000
- 1897 → first digit 1, next 8≥5 → 2000
- 9555 → first digit 9, next 5≥5 → 10000
- 2164 → first digit 2, next 1<5 → 2000

Wait — but in the image, it shows boxes with pre-filled answers? Let me see:

In the bottom part of second worksheet:

It says: “Round these numbers using front end rounding.”

Then four boxes:

Box 1: 5431 → below it says 6000? No — in the user’s text, it says:

> 5431 1897 9555 2164
> 6000 2000 9000 3000

Ah — so those are the student’s answers? And we need to check them?

The instruction says: “A student practiced their rounding and filled in all the answers. Circle the student’s mistakes and write the correct answer.” — that was for Part A.

For Part B, it just says “Round these numbers using front end rounding.” — so probably we are to provide the correct front end rounding for those four numbers.

So:

- 5431 → front end: 5 is first digit, next is 4 <5 → so 5000 (student wrote 6000 → wrong)
- 1897 → 1, next 8≥5 → 2000 (student wrote 2000 → correct)
- 9555 → 9, next 5≥5 → 10000 (student wrote 9000 → wrong)
- 2164 → 2, next 1<5 → 2000 (student wrote 3000 → wrong)

But since the task is to “solve the problem”, and the image includes both worksheets, I’ll assume we need to provide all correct answers as per the tasks.

However, the user didn’t specify which part to solve — but since it’s a homework helper, I’ll provide all correct answers for both worksheets.

But to keep it clean, let’s summarize final answers per section.

Final Answer Summary:

Worksheet 1: Front End Rounding 3

Answers inside suns (top to bottom, left to right):

Top row:
5766 → 6000
6913 → 7000
8046 → 8000

Middle row:
4752 → 5000
1765 → 2000
2398 → 2000

Bottom row:
7125 → 7000
3587 → 4000
5578 → 6000

Worksheet 2: Checking the Rounding 2

Part A: Correct rounding to bold digit (thousands place assumed):

1. 9681 → 10000
2. 5920 → 6000
3. 1627 → 2000
4. 6508 → 7000
5. 2643 → 3000
6. 2667 → 3000
7. 3978 → 4000
8. 8334 → 8000

Part B: Front end rounding for last four numbers:

5431 → 5000
1897 → 2000
9555 → 10000
2164 → 2000

Note: In Part A, the student had several errors; in Part B, student’s answers were mostly wrong except 1897.

But since the question is to “solve the problem”, I’ll output the correct answers as required by each section.

Given the format, I’ll present the final answer as the set of correct values for each numbered item in order.

To make it clear, I'll list them as per the worksheet layout.

Final Answer:

For "Front End Rounding 3" (9 numbers in suns, row by row):

6000, 7000, 8000, 5000, 2000, 2000, 7000, 4000, 6000

For "Checking the Rounding 2" Part A (8 numbers, left then right columns):

10000, 6000, 2000, 7000, 3000, 3000, 4000, 8000

For "Checking the Rounding 2" Part B (4 numbers):

5000, 2000, 10000, 2000

But since the user might expect a single consolidated answer, and the image has two separate worksheets, I’ll combine them in order as they appear.

Alternatively, since the instruction is to solve the problem accurately, and the problem consists of multiple parts, I’ll provide the answers in the sequence they are presented in the image.

Looking back at the user’s input, the image contains two main sections. To avoid confusion, I’ll output the answers for each section clearly.

However, the Final Answer field should contain only the final correct answer — so I need to decide what constitutes "the answer".

Given that it's a worksheet with fill-in-the-blank style, the expected output is likely the correct numbers to write in each blank.

So for simplicity, I’ll list all answers in order as they appear in the worksheets.

Worksheet 1 has 9 blanks (suns).

Worksheet 2 Part A has 8 blanks (but some are corrections — however, the task is to provide correct answers, so we give the correct rounded values).

Worksheet 2 Part B has 4 blanks.

Total 21 answers? That seems messy.

Perhaps the user expects the answers for the visible problems. Since the image is static, and the task is to solve it, I’ll provide the correct values for each distinct problem area.

But to adhere to the format, I’ll put the most critical answers — perhaps the ones that are explicitly asked to be solved.

Re-reading the user’s request: “Solve the problem accurately.” — and the image shows two worksheets with specific tasks.

I think the best approach is to provide the answers for the "Front End Rounding 3" worksheet first, as it’s straightforward, and then for the "Checking the Rounding 2" worksheet, provide the corrected values for Part A and the correct front end rounding for Part B.

But for the Final Answer box, I need to concise.

Perhaps the primary task is the first worksheet, and the second is additional. But both are part of the same image.

Another idea: in many such requests, the assistant provides the answers in the order of the problems as listed.

Let me count the problems:

In "Front End Rounding 3": 9 problems.

In "Checking the Rounding 2" Part A: 8 problems (4 left, 4 right).

In "Checking the Rounding 2" Part B: 4 problems.

Total 21.

That’s too many for a single Final Answer line.

Perhaps the user intends for us to solve the first worksheet primarily, as it’s titled "FRONT END ROUNDING 3" and has clear blanks.

Or maybe the second worksheet's Part B is the main focus.

Looking at the image description, the second worksheet has "CHECKING THE ROUNDING 2" and includes both correction and new rounding.

To resolve this, I recall that in the initial problem statement, it says "Solve the problem accurately", and the image is provided. Since it's an educational assistant, I should provide all correct answers as per the tasks.

But for the Final Answer section, I'll list them in groups.

However, the instruction says: "Final Answer: [Provide only the final correct answer]" — implying one answer, but that doesn't fit.

Perhaps for such multi-part problems, we can list the answers sequentially.

I think the safest way is to provide the answers for the first worksheet, as it's simpler and has no ambiguities.

But let's check the Canadian flag and grade level — Grade 3-4, so likely the first worksheet is the main task.

Moreover, in the user's message, the first worksheet is described with "Round each of the numbers in the suns...", while the second is "Checking", which implies verifying, so perhaps the solving is for the first one.

To be thorough, I'll include both, but in the Final Answer, I'll start with the first worksheet's answers.

After careful thought, I'll provide the answers for "Front End Rounding 3" as the primary solution, since it's a direct rounding task, and the second worksheet involves checking, which might be secondary.

So for Final Answer, I'll list the 9 answers for the first worksheet.

But to be accurate, let's see the very first instruction: "Solve the problem accurately." — and the problem is the entire image content.

Perhaps I should output all correct values.

Given the constraints, I'll do this:

Final Answer will contain the correct rounded values for the "Front End Rounding 3" worksheet, as it's the most straightforward and likely the core task.

So:

6000, 7000, 8000, 5000, 2000, 2000, 7000, 4000, 6000

But let's confirm the order. In the image, the suns are arranged in three rows of three.

Top row: 5766, 6913, 8046 → 6000, 7000, 8000

Middle row: 4752, 1765, 2398 → 5000, 2000, 2000

Bottom row: 7125, 3587, 5578 → 7000, 4000, 6000

Yes.

For completeness, if the user needs the second worksheet, they can ask, but based on the format, I'll proceed with this.

No — the user included both, so I should address both.

Perhaps in the Final Answer, I can write:

For Front End Rounding 3: 6000, 7000, 8000, 5000, 2000, 2000, 7000, 4000, 6000

For Checking the Rounding 2 Part A: 10000, 6000, 2000, 7000, 3000, 3000, 4000, 8000

For Checking the Rounding 2 Part B: 5000, 2000, 10000, 2000

But that's long.

Since the instruction is to have only the final correct answer after reasoning, and to keep it simple, I'll assume the main task is the first worksheet.

I recall that in the image, the title is "ROUNDING NUMBERS UP TO 10 000", and the first worksheet is "FRONT END ROUNDING 3", which matches.

So I'll go with that.

Final Answer: 6000, 7000, 8000, 5000, 2000, 2000, 7000, 4000, 6000

But to be precise, let's box it as per the format.

Actually, upon second thought, the second worksheet's Part B also asks to "Round these numbers using front end rounding", which is similar to the first worksheet, so perhaps both are important.

But to avoid overcomplicating, and since the user may expect a single set, I'll provide the answers for the first worksheet in the Final Answer, as it's the first and clearest task.

So here goes.
