Place Value online exercise for Grade 4 - Free Printable

Let's solve each part of this Place Value worksheet step by step and explain the reasoning.

Part 1: Write the number using the expanded form

We add the values together to get the standard form number.

1) $700 + 50 + 8 = 758$
2) $100 + 60 + 2 = 162$
3) $400 + 90 + \boxed{?}$ → Wait, missing a number. But since it’s just “+”, we assume it's meant to be $400 + 90 + 0 = 490$, but likely a typo. Let's assume it's 400 + 90 + 0 = 490, or maybe the problem is incomplete. But based on pattern, probably meant to be $400 + 90 + 0$, so:
→ $400 + 90 = 490$

But wait — actually, looking at the layout:

> 3) 400 + 90 + = [box]
> So there's no number after "+", which is likely an error. However, in context, perhaps it's meant to be 400 + 90 + 0, or maybe it's a typo and should be like others. But let's suppose it's 400 + 90 + 0 = 490.

But more likely, it's a formatting issue. Let's assume it's 400 + 90 + 0 = 490, unless otherwise specified.

But checking other problems, they have full numbers. So possibly a typo. We'll go with 490 as answer.

4) $80 + 5 = 85$
5) $900 + 70 + 7 = 977$
6) $800 + 30 + 4 = 834$
7) $500 + 3 = 503$
8) $600 + 10 + 3 = 613$

✔ Answers for Part 1:
1) 758
2) 162
3) 490 (assuming missing digit is 0)
4) 85
5) 977
6) 834
7) 503
8) 613

Part 2: Write the correct number in the box

We break down the number into hundreds, tens, and ones.

Example: $475 = 400 + \boxed{70} + 5$

9) $573 = 500 + \boxed{70} + 3$
→ 573 - 500 - 3 = 70 → ✔

10) $826 = \boxed{800} + 20 + 6$
→ 826 - 20 - 6 = 800 → ✔

11) $219 = 200 + 10 + \boxed{9}$
→ 219 - 200 - 10 = 9 → ✔

12) $357 = 300 + 50 + \boxed{7}$
→ 357 - 300 - 50 = 7 → ✔

13) $702 = 700 + \boxed{0} + 2$
→ 702 - 700 - 2 = 0 → ✔

14) $499 = 400 + \boxed{90} + 9$
→ 499 - 400 - 9 = 90 → ✔

✔ Answers for Part 2:
9) 70
10) 800
11) 9
12) 7
13) 0
14) 90

Part 3: Fill in the correct digit for each place value

We identify how many hundreds, tens, and ones are in each number.

Example: $348 = 3$ hundreds + $4$ tens + $8$ ones

15) $819 = \boxed{8}$ hundreds + $\boxed{1}$ tens + $\boxed{9}$ ones
→ 800 + 10 + 9 = 819 → ✔

16) $407 = \boxed{4}$ hundreds + $\boxed{0}$ tens + $\boxed{7}$ ones
→ 400 + 0 + 7 = 407 → ✔

17) $539 = \boxed{5}$ hundreds + $\boxed{3}$ tens + $\boxed{9}$ ones
→ 500 + 30 + 9 = 539 → ✔

18) $721 = \boxed{7}$ hundreds + $\boxed{2}$ tens + $\boxed{1}$ ones
→ 700 + 20 + 1 = 721 → ✔

✔ Final Answer Key:

#### Part 1: Expanded Form
1) 758
2) 162
3) 490 *(assumed missing digit is 0)*
4) 85
5) 977
6) 834
7) 503
8) 613

#### Part 2: Fill in Missing Number
9) 70
10) 800
11) 9
12) 7
13) 0
14) 90

#### Part 3: Place Value Digits
15) 8 hundreds + 1 ten + 9 ones
16) 4 hundreds + 0 tens + 7 ones
17) 5 hundreds + 3 tens + 9 ones
18) 7 hundreds + 2 tens + 1 ones

🔍 Explanation Summary:

- Expanded form means writing a number as the sum of its place values (e.g., 700 + 50 + 8 = 758).
- To find missing parts in equations like $573 = 500 + \boxed{} + 3$, subtract known values: $573 - 500 - 3 = 70$.
- For place value breakdowns, look at each digit:
- The leftmost digit is hundreds, next is tens, last is ones.
- For example, in 407:
- 4 → hundreds
- 0 → tens
- 7 → ones

This helps students understand how numbers are built from their digits.
