## 🔢 Part 1: Round each number to the nearest hundred

Rule for rounding to the nearest hundred:

Look at the tens digit (the second digit from the right).
- If it’s 5 or greater, round up.
- If it’s 4 or less, round down.

---

✔ 264 →
- Tens digit = 6 → ≥5 → Round up
- 264 → 300

✔ 85 →
- Tens digit = 8 → ≥5 → Round up
- 85 → 100

✔ 545 →
- Tens digit = 4 → ≤4 → Round down
- 545 → 500

✔ 239 →
- Tens digit = 3 → ≤4 → Round down
- 239 → 200

✔ 350 →
- Tens digit = 5 → ≥5 → Round up
- 350 → 400

✔ 834 →
- Tens digit = 3 → ≤4 → Round down
- 834 → 800

📌 Answers for Part 1:
```
264 - 300
85 - 100
545 - 500
239 - 200
350 - 400
834 - 800
```

## 🫧 Part 2: Bubble Numbers — Which two round to 700? Which two round to 600?

Bubble numbers:
572, 748, 650, 635, 762, 804

Let’s round each:

- 572 → tens digit = 7 → round up → 600
- 748 → tens digit = 4 → round down → 700
- 650 → tens digit = 5 → round up → 700
- 635 → tens digit = 3 → round down → 600
- 762 → tens digit = 6 → round up → 800
- 804 → tens digit = 0 → round down → 800

✔ So:
- Round to 700: 748 and 650
- Round to 600: 572 and 635

## 🌀 Part 3: Write 4 numbers that round to 400

We need numbers that round to 400 when rounded to the nearest hundred.

That means numbers from 350 to 449 (inclusive).

Why?
- 350 → rounds up to 400 (tens digit = 5)
- 449 → rounds down to 400 (tens digit = 4)

So pick any 4 numbers in that range.

Examples:
- 350
- 375
- 400
- 449

(You can choose others like 362, 399, 410, etc.)

The worksheet has circles with digits: 3, 4, 2, 7 — probably suggesting you use those digits to form numbers that round to 400.

Let’s try using those digits:

Possible numbers:
- 372 → tens digit = 7 → rounds to 400 ✔
- 327 → tens digit = 2 → rounds to 300 ✘
- 427 → tens digit = 2 → rounds to 400 ✔
- 472 → tens digit = 7 → rounds to 500 ✘
- 374 → tens digit = 7 → rounds to 400 ✔
- 437 → tens digit = 3 → rounds to 400 ✔

So good choices using those digits:
→ 372, 427, 374, 437

But since the worksheet says “Write 4 numbers”, you can write any 4 that round to 400.

📌 Sample Answer:
```
350, 375, 400, 449
```
*(or using given digits: 372, 427, 374, 437)*

## ✔ Part 4: True or False

1. 765 rounds to 700.

- Tens digit = 6 → round up → 800
- So, 765 → 800, NOT 700 → ✘ False

2. 829 rounds to 800.

- Tens digit = 2 → round down → 800 ✔ → True

3. 109 rounds to 100.

- Tens digit = 0 → round down → 100 ✔ → True

---

📌 Answers for Part 4:
```
765 rounds to 700. → False
829 rounds to 800. → True
109 rounds to 100. → True
```
