4th Grade Place Value Worksheets - Free Printable

Let's solve each problem step by step, converting the given expanded forms into standard form (i.e., regular numbers).

We'll break down each part based on place value:

- Ten thousands → ×10,000
- Thousands → ×1,000
- Hundreds → ×100
- Tens → ×10
- Ones → ×1

Also, note that if a number like "14 tens" is given, we convert it to:
14 × 10 = 140, and then add accordingly.

Example Given:

7 ten thousands + 3 thousands + 18 tens =
= 7×10,000 = 70,000
+ 3×1,000 = 3,000
+ 18×10 = 180
Total = 70,000 + 3,000 + 180 = 73,180 ✔

Now let’s solve each one:

---

1) 8 thousands + 14 tens + 5 ones

= 8×1,000 = 8,000
+ 14×10 = 140
+ 5 = 5
→ 8,000 + 140 + 5 = 8,145

---

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

= 15×1,000 = 15,000
+ 6×100 = 600
+ 5×10 = 50
+ 9 = 9
→ 15,000 + 600 + 50 + 9 = 15,659

---

3) 4 ten thousands + 13 hundreds + 5 ones

= 4×10,000 = 40,000
+ 13×100 = 1,300
+ 5 = 5
→ 40,000 + 1,300 + 5 = 41,305

---

4) 2 ten thousands + 8 hundreds + 29 ones

= 2×10,000 = 20,000
+ 8×100 = 800
+ 29 = 29
→ 20,000 + 800 + 29 = 20,829

---

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

= 72×1,000 = 72,000
+ 5×100 = 500
+ 8×10 = 80
+ 2 = 2
→ 72,000 + 500 + 80 + 2 = 72,582

---

6) 6 ten thousands + 28 hundreds + 4 tens

= 6×10,000 = 60,000
+ 28×100 = 2,800
+ 4×10 = 40
→ 60,000 + 2,800 + 40 = 62,840

---

7) 8 ten thousands + 2 hundreds + 9 ones

= 8×10,000 = 80,000
+ 2×100 = 200
+ 9 = 9
→ 80,000 + 200 + 9 = 80,209

---

8) 37 thousands + 6 tens

= 37×1,000 = 37,000
+ 6×10 = 60
→ 37,000 + 60 = 37,060

---

9) 4 ten thousands + 28 hundreds + 15 ones

= 4×10,000 = 40,000
+ 28×100 = 2,800
+ 15 = 15
→ 40,000 + 2,800 + 15 = 42,815

---

10) 36 thousands + 9 hundreds + 23 ones

= 36×1,000 = 36,000
+ 9×100 = 900
+ 23 = 23
→ 36,000 + 900 + 23 = 36,923

---

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

= 5×10,000 = 50,000
+ 1×1,000 = 1,000
+ 22×10 = 220
+ 8 = 8
→ 50,000 + 1,000 + 220 + 8 = 51,228

---

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

= 9×10,000 = 90,000
+ 47×100 = 4,700
+ 3×10 = 30
+ 6 = 6
→ 90,000 + 4,700 + 30 + 6 = 94,736

---

13) 2 ten thousands + 63 tens

= 2×10,000 = 20,000
+ 63×10 = 630
→ 20,000 + 630 = 20,630

---

14) 4 ten thousands + 12 hundreds + 7 ones

= 4×10,000 = 40,000
+ 12×100 = 1,200
+ 7 = 7
→ 40,000 + 1,200 + 7 = 41,207

---

15) 68 thousands + 9 hundreds + 53 ones

= 68×1,000 = 68,000
+ 9×100 = 900
+ 53 = 53
→ 68,000 + 900 + 53 = 68,953

---

16) 7 ten thousands + 28 tens + 4 ones

= 7×10,000 = 70,000
+ 28×10 = 280
+ 4 = 4
→ 70,000 + 280 + 4 = 70,284

---

17) 2 ten thousands + 6 thousands + 7 hundreds + 62 ones

= 2×10,000 = 20,000
+ 6×1,000 = 6,000
+ 7×100 = 700
+ 62 = 62
→ 20,000 + 6,000 + 700 + 62 = 26,762

---

18) 1 ten thousand + 46 hundreds + 3 ones

= 1×10,000 = 10,000
+ 46×100 = 4,600
+ 3 = 3
→ 10,000 + 4,600 + 3 = 14,603

---

19) 5 ten thousands + 86 hundreds + 19 ones

= 5×10,000 = 50,000
+ 86×100 = 8,600
+ 19 = 19

---

20) 8 ten thousands + 17 hundreds + 5 tens

= 8×10,000 = 80,000
+ 17×100 = 1,700
+ 5×10 = 50
→ 80,000 + 1,700 + 50 = 81,750

🔍 Key Tips:

- Always convert groups (like 14 tens = 140) before adding.
- Combine values from largest to smallest place value.
- Be careful with carrying over when adding — but here, since we're just converting, no need for actual addition unless you're doing it manually.
