4th Grade Place Value Worksheet - Practice identifying place values, writing numbers in expanded and standard forms.

Let’s work through each part of the worksheet step by step.

Part 1: Write the place value of the underlined digit

We need to identify what place (ones, tens, hundreds, etc.) the underlined digit is in for each number.

Section a:

a) 72,264 — The underlined digit is 6.
→ It’s in the tens place → Place value = Tens

b) 428,188 — Underlined digit is 8 (the second one from right).
→ That’s the tens place → Tens

c) 28,816 — Underlined digit is 8 (first 8 from left? Wait — looking at formatting: “28,816” — likely the first 8 is underlined? But in text it's written as "28,816" with underline on first 8? Actually, in original image, probably the *second* 8 is underlined? Let me check standard interpretation.

Wait — since we can’t see the actual underline visually here, but based on common worksheets and the way numbers are presented:

Looking again:

In section a:
- 72,264 → underline under 6 → tens
- 428,188 → underline under last 8 → tens
- 28,816 → underline under first 8? Or second? In many fonts, if written as “28,816”, and underline under the 8 after comma — that would be thousands? Wait no — let’s break down:

Actually, better to assume the underline is shown in the image — since I’m an AI, I must rely on typical presentation.

But since user provided text version, and said “underlined digit”, I’ll go by position as typically marked.

Alternatively, perhaps in the original image:

For “28,816” — if the underline is under the first 8 (ten-thousands?), or the second 8 (hundreds?).

Wait — let’s look at all:

Actually, to avoid confusion, I’ll use standard positional analysis assuming the underline is on the digit as commonly emphasized in such worksheets.

But since this is critical, let me re-express:

Perhaps the best approach is to list each number and note which digit is underlined based on common patterns.

Actually — looking back at the problem statement: “Write the place value of the underlined digit below the numbers”

And in the table, for example:

Row a:
- 72,264 → underline under 6 → tens
- 428,188 → underline under 8 (last digit before units? No — 428,188 — digits: hundred thousands, ten thousands, thousands, hundreds, tens, ones → so if underline under the 8 in tens place → tens
- 28,816 → if underline under 8 (which one?) — likely the 8 in hundreds place? Because 28,816: 2=ten thousands, 8=thousands, 8=hundreds, 1=tens, 6=ones → if underline under the second 8 → hundreds
- 137,295 → underline under 7 → thousands? 1=Hundred thousands, 3=Ten thousands, 7=Thousands → yes → Thousands
- 29,138 → underline under 8 → ones → Ones

Similarly for section b:

b)
- 637,921 → underline under 7 → thousands? 6=Hundred thousands, 3=Ten thousands, 7=Thousands → Thousands
- 59,224 → underline under 9 → thousands? 5=Ten thousands, 9=Thousands → Thousands
- 39,424 → underline under 9 → thousands? 3=Ten thousands, 9=Thousands → Thousands
- 962,508 → underline under 6 → ten thousands? 9=Hundred thousands, 6=Ten thousands → Ten Thousands
- 108,392 → underline under 2 → ones → Ones

Wait — but in 108,392, if underline under 2, that’s ones.

But let’s confirm with logic.

Actually, to be precise, I think there might be a mistake in my assumption. Since I don’t have visual, I’ll proceed with most logical placements based on common worksheet designs.

But to ensure accuracy, let’s take each one carefully:

Assume the underline is on the digit as follows (based on typical emphasis):

Section a:
a) 72,264 → underline on 6 → tens → Tens
b) 428,188 → underline on the 8 in tens place → Tens
c) 28,816 → underline on the 8 in hundreds place → Hundreds (since 28,816: positions: 2=10k, 8=1k, 8=100s, 1=10s, 6=1s)
d) 137,295 → underline on 7 → thousands → Thousands
e) 29,138 → underline on 8 → ones → Ones

Section b:
a) 637,921 → underline on 7 → thousands → Thousands
b) 59,224 → underline on 9 → thousands → Thousands
c) 39,424 → underline on 9 → thousands → Thousands
d) 962,508 → underline on 6 → ten thousands → Ten Thousands
e) 108,392 → underline on 2 → ones → Ones

This seems consistent.

Part 2: Expanded Form

Expanded form means writing the number as sum of each digit times its place value.

a) 64,236
= 60,000 + 4,000 + 200 + 30 + 6

b) 884,137
= 800,000 + 80,000 + 4,000 + 100 + 30 + 7

c) 44,119
= 40,000 + 4,000 + 100 + 10 + 9

d) 931,447
= 900,000 + 30,000 + 1,000 + 400 + 40 + 7

---

Part 3: Standard Form

Add up the parts to get the full number.

a) 30,000 + 6,000 + 600 + 50 + 9
= 36,659

b) 800,000 + 7,000 + 200 + 50 + 6
= 807,256

c) 500,000 + 5,000 + 100 + 40 + 2
= 505,142

d) 90,000 + 1,000 + 200 + 30 + 8
= 91,238
