4th Grade Place Value Worksheets - Free Printable

Sure! Let’s solve each problem step by step. The goal is to convert the given expanded form (in terms of thousands, hundreds, tens, and ones) into standard form — that is, a regular number like 12,345.

We’ll use place value:
- 1 ten thousand = 10,000
- 1 thousand = 1,000
- 1 hundred = 100
- 1 ten = 10
- 1 one = 1

Sometimes we have more than 9 in a place (like 14 tens or 28 hundreds), so we need to regroup — just like carrying in addition.

Let’s go one by one:

---

1) 8 thousands + 14 tens + 5 ones

- 8 thousands = 8,000
- 14 tens = 140 → which is 1 hundred and 4 tens → so we regroup: add 1 to hundreds, leave 4 in tens
- 5 ones = 5

→ So: 8,000 + 100 + 40 + 5 = 8,145

✔ Answer: 8,145

---

2) 15 thousands + 6 hundreds + 5 tens + 9 ones

- 15 thousands = 15,000
- 6 hundreds = 600
- 5 tens = 50
- 9 ones = 9

→ Add them: 15,000 + 600 = 15,600; +50 = 15,650; +9 = 15,659

✔ Answer: 15,659

---

3) 4 ten thousands + 13 hundreds + 5 ones

- 4 ten thousands = 40,000
- 13 hundreds = 1,300 → which is 1 thousand and 3 hundreds → regroup!
- 5 ones = 5

→ So: 40,000 + 1,000 = 41,000; + 300 = 41,300; +5 = 41,305

✔ Answer: 41,305

---

4) 2 ten thousands + 8 hundreds + 29 ones

- 2 ten thousands = 20,000
- 8 hundreds = 800
- 29 ones = 29 → which is 2 tens and 9 ones → regroup!

→ So: 20,000 + 800 = 20,800; + 20 = 20,820; +9 = 20,829

✔ Answer: 20,829

---

5) 72 thousands + 5 hundreds + 8 tens + 2 ones

- 72 thousands = 72,000
- 5 hundreds = 500
- 8 tens = 80
- 2 ones = 2

→ 72,000 + 500 = 72,500; +80 = 72,580; +2 = 72,582

✔ Answer: 72,582

---

6) 6 ten thousands + 28 hundreds + 4 tens

- 6 ten thousands = 60,000
- 28 hundreds = 2,800 → which is 2 thousands and 8 hundreds → regroup!
- 4 tens = 40

→ So: 60,000 + 2,000 = 62,000; + 800 = 62,800; +40 = 62,840

✔ Answer: 62,840

---

7) 8 ten thousands + 2 hundreds + 9 ones

- 8 ten thousands = 80,000
- 2 hundreds = 200
- 9 ones = 9

→ 80,000 + 200 = 80,200; +9 = 80,209

✔ Answer: 80,209

---

8) 37 thousands + 6 tens

- 37 thousands = 37,000
- 6 tens = 60

→ 37,000 + 60 = 37,060

✔ Answer: 37,060

---

9) 4 ten thousands + 28 hundreds + 15 ones

- 4 ten thousands = 40,000
- 28 hundreds = 2,800 → 2 thousands + 8 hundreds
- 15 ones = 15 → 1 ten + 5 ones

→ Regroup: 40,000 + 2,000 = 42,000; +800 = 42,800; +10 = 42,810; +5 = 42,815

✔ Answer: 42,815

---

10) 36 thousands + 9 hundreds + 23 ones

- 36 thousands = 36,000
- 9 hundreds = 900
- 23 ones = 23 → 2 tens + 3 ones

→ 36,000 + 900 = 36,900; +20 = 36,920; +3 = 36,923

✔ Answer: 36,923

---

11) 5 ten thousands + 1 thousand + 22 tens + 8 ones

- 5 ten thousands = 50,000
- 1 thousand = 1,000
- 22 tens = 220 → 2 hundreds + 2 tens
- 8 ones = 8

→ 50,000 + 1,000 = 51,000; +200 = 51,200; +20 = 51,220; +8 = 51,228

✔ Answer: 51,228

---

12) 9 ten thousands + 47 hundreds + 3 tens + 6 ones

- 9 ten thousands = 90,000
- 47 hundreds = 4,700 → 4 thousands + 7 hundreds
- 3 tens = 30
- 6 ones = 6

→ 90,000 + 4,000 = 94,000; +700 = 94,700; +30 = 94,730; +6 = 94,736

✔ Answer: 94,736

💡 Key Tip:

Always check if any group (tens, hundreds, etc.) has more than 9 — then regroup! For example:
- 14 tens → 1 hundred + 4 tens
- 28 hundreds → 2 thousands + 8 hundreds
- 63 tens → 6 hundreds + 3 tens

This is just like “carrying” in addition — it ensures each digit in standard form is between 0–9.
