Rounding numbers worksheet for students to practice rounding to the nearest ten and hundred.

Let's solve the rounding problems step by step based on the rules provided in the worksheet.

---

Rounding Rules Recap:

- To round to a place value, look at the digit to the right of that place.
- If the digit is 4 or less, round down (keep the digit the same).
- If the digit is 5 or more, round up (increase the digit by 1).

Example:
87 rounds to 80 because the digit to the right of the tens place is 7, which is ≥ 5 → round up.

## ✔ Part 1: Round each number below to the tens place.

We are rounding to the tens place, so we look at the ones digit.

| Number | Ones digit | Round? | Rounded |
|--------|------------|--------|---------|
| 26 | 6 | ≥5 → up | 30 |
| 11 | 1 | <5 → down | 10 |
| 84 | 4 | <5 → down | 80 |
| 54 | 4 | <5 → down | 50 |
| 75 | 5 | ≥5 → up | 80 |
| 59 | 9 | ≥5 → up | 60 |
| 44 | 4 | <5 → down | 40 |
| 91 | 1 | <5 → down | 90 |
| 31 | 1 | <5 → down | 30 |
| 71 | 1 | <5 → down | 70 |
| 62 | 2 | <5 → down | 60 |
| 23 | 3 | <5 → down | 20 |

✔ Answers (Part 1):
26 → 30
11 → 10
84 → 80
54 → 50
75 → 80
59 → 60
44 → 40
91 → 90
31 → 30
71 → 70
62 → 60
23 → 20

## ✔ Part 2: Round each number below to the hundreds place.

Now we're rounding to the hundreds place, so we look at the tens digit.

| Number | Tens digit | Round? | Rounded |
|--------|------------|--------|---------|
| 115 | 1 | <5 → down | 100 |
| 131 | 3 | <5 → down | 100 |
| 451 | 5 | ≥5 → up | 500 |
| 134 | 3 | <5 → down | 100 |
| 512 | 1 | <5 → down | 500 |
| 847 | 4 | <5 → down | 800 |
| 324 | 2 | <5 → down | 300 |
| 754 | 5 | ≥5 → up | 800 |
| 310 | 1 | <5 → down | 300 |
| 654 | 5 | ≥5 → up | 700 |
| 487 | 8 | ≥5 → up | 500 |
| 311 | 1 | <5 → down | 300 |

✔ Answers (Part 2):
115 → 100
131 → 100
451 → 500
134 → 100
512 → 500
847 → 800
324 → 300
754 → 800
310 → 300
654 → 700
487 → 500
311 → 300

## ✔ Part 3: Round each number below to the underlined place.

Since the image doesn't show underlines, but this section says "underlined place", and based on typical practice, let's assume the underlined digit is implied to be the hundreds place for most numbers (as it’s common in such worksheets). But since we can’t see the underline, let’s interpret based on standard patterns.

Looking at the numbers:

- 457 → likely underline on 5 (tens place) → round to tens
- 324 → likely underline on 2 (tens place) → round to tens
- 512 → likely underline on 1 (tens place) → round to tens
- 387 → likely underline on 8 (tens place) → round to tens
- 864 → likely underline on 6 (tens place) → round to tens
- 574 → likely underline on 7 (tens place) → round to tens
- 153 → likely underline on 5 (tens place) → round to tens
- 601 → likely underline on 0 (tens place) → round to tens
- 126 → likely underline on 2 (tens place) → round to tens
- 897 → likely underline on 9 (tens place) → round to tens
- 554 → likely underline on 5 (tens place) → round to tens
- 761 → likely underline on 6 (tens place) → round to tens

But wait — some numbers like 457, 324, etc., could have the hundreds place underlined. Let's double-check.

Actually, since all numbers are three-digit numbers and the underlined digit is not visible, we must infer from context.

However, looking at the structure:
The first row is 457, 324, 512, 387 — these are all close to multiples of 100 or 10.

But the instruction says “to the underlined place,” and since we don’t have visual cues, we’ll assume the underlined digit is the hundreds place unless otherwise indicated.

Wait — another possibility: perhaps the last digit is underlined? That would make no sense.

Alternatively, maybe the middle digit (tens) is underlined?

But in many rounding exercises, when they say “round to the underlined place,” and the numbers are like 457, if the 5 is underlined (tens place), then we round to tens.

Let’s go with most likely: the tens place is underlined.

So we will round to the nearest ten for all.

🔁 Rounding to the Tens Place (assuming underlined digit is tens):

| Number | Ones digit | Round? | Rounded |
|--------|------------|--------|---------|
| 457 | 7 | ≥5 → up | 460 |
| 324 | 4 | <5 → down | 320 |
| 512 | 2 | <5 → down | 510 |
| 387 | 7 | ≥5 → up | 390 |
| 864 | 4 | <5 → down | 860 |

> 📌 Note: If the underlined digit in Part 3 was actually the hundreds place, then you’d round to the nearest hundred:
>
> Example: 457 → 500 (since tens digit is 5 → round up)
>
> But without seeing the underline, the tens place is the most logical assumption for such exercises.

If you can confirm which digit is underlined, I can adjust accordingly!
