This worksheet helps students practice identifying the value of digits in three-digit numbers and converting between standard and expanded forms.

Let's solve the worksheet step by step. This is a Place Value: Three-Digit Numbers worksheet, and it includes several types of problems:

---

Part 1: Write the value of the underlined digit

We need to identify the place value (hundreds, tens, or ones) of the underlined digit.

1. 037 → The underlined digit is 3, which is in the tens place.
→ Value = 30

2. 198 → Underlined digit is 9, in the tens place.
→ Value = 90

3. 412 → Underlined digit is 1, in the tens place.
→ Value = 10

4. 849 → Underlined digit is 8, in the hundreds place.
→ Value = 800

5. 752 → Underlined digit is 5, in the tens place.
→ Value = 50

6. 528 → Underlined digit is 5, in the hundreds place.
→ Value = 500

7. 335 → Underlined digit is 3, in the hundreds place.
→ Value = 300

8. 916 → Underlined digit is 9, in the hundreds place.
→ Value = 900

9. 292 → Underlined digit is 9, in the tens place.
→ Value = 90

Part 2: Write each number in standard form

We convert expanded forms into standard (numerical) form.

10. 200 + 10 + 3 = 213
11. 500 + 40 + 7 = 547
12. 300 + 90 + 1 = 391
13. 700 + 50 + 6 = 756
14. 900 + 30 + 4 = 934
15. 100 + 20 + 7 = 127
16. 600 + 10 + 6 = 616
17. 200 + 60 + 8 = 268
18. 800 + 30 + 3 = 833
19. 400 + 40 + 4 = 444

Part 3: Word Form to Standard Form

20. "four hundred sixty-eight" → 468

✔ Answer: 468

Part 4: Write each number in expanded form

Now we break down numbers into hundreds, tens, and ones.

21. 413 = 400 + 10 + 3
22. 503 = 500 + 0 + 3 → But usually written as 500 + 0 + 3, or just 500 + 3 (though both are acceptable; the full form includes tens).
→ Better: 500 + 0 + 3
23. 215 = 200 + 10 + 5

✔ Answers for Part 4:
21. 400 + 10 + 3
22. 500 + 0 + 3
23. 200 + 10 + 5
