4th grade place value worksheet answers: worksheet problems 1 to 10

1 – Value of a digit

Name the places from the left: 3 ten thousands, 9 thousands, 4 hundreds, 5 tens, 0 ones.

The 9 is in the thousands place, so its value is \(9 \times 1{,}000 = 9{,}000\).

9,000

2 – Name the place

Count places from the right: 9 ones, 1 tens, 4 hundreds, 3 thousands, 7 ten thousands.

So, the 7 is in the ten thousands place.

3 – Value in a big number

The 6 is in the ten thousands column.

The chart shows 6 in the ten thousands column.

\(6 \times 10{,}000 = 60{,}000\)

60,000

4 – Ten times as much

Multiply by 10: \(400 \times 10 = 4{,}000\).

Check: the 4 moves one place to the left, from hundreds to thousands.

4,000

5 – Compare two sevens

Ten bars of 70 make 700.

The diagram shows ten bars of 70 in 700.

\(700 \div 70 = 10\)

10 times as much

6 – Two sixes in a row

First 6: \(600{,}000\). Second 6: \(60{,}000\).

\(600{,}000 \div 60{,}000 = 10\)

10 times as much

7 – Expanded form

6 thousands, 2 hundreds, 0 tens, 5 ones.

\(6{,}000 + 200 + 5\)

\(6{,}000 + 200 + 5\)

Worksheet problem 8 and after

8 – Standard form from expanded

4 ten thousands, 3 thousands, 6 hundreds, 0 tens, 8 ones.

\(43,608\)

9 – Word form

Read each period. 52 thousand, then 14.

fifty-two thousand, fourteen

10 – Standard form from words

306 thousand and 40. The hundreds place has no value, so it is 0, and the ones place is 0.

\(306{,}000 + 40 = 306{,}040\)

\(306,040\)

Worksheet problems 11 and up

11 – Compare thousands

Thousands and hundreds match (4 and 5). In the tens place, 0 is less than 9.

\(4{,}509 < 4{,}590\)

12 – Compare six-digit numbers

The digits match through the hundreds place (1, 2, 0, 3). In the tens place, 6 is greater than 4.

\(120{,}364 > 120{,}346\)

13 – Order from least to greatest

The ten thousands digits are 5, 5, and 5, so compare the thousands: 6, 6, and 8. Therefore \(58,062\) is greatest.

For \(56,820\) and \(56,082\), the hundreds are 8 and 0, so \(56,082\) is less.

\(56,082\), \(56,820\), \(58,062\)

14 – Read the chart

The chart reads 2, 0, 8, 4, 1, 5 from left to right: \(208,415\).

Also, the highlighted 4 is in the hundreds column, so its value is \(4 \times 100 = 400\).

\(208,415\); 400

15 – Stadium crowd

\(12,486\): 1 ten thousand, 2 thousands, 4 hundreds, 8 tens, 6 ones.

The 2 is worth \(2 \times 1{,}000 = 2{,}000\).

Word form: twelve thousand, four hundred eighty-six.

2,000; twelve thousand, four hundred eighty-six

16 – Mystery number

Standard form: 8, 3, 0, 7, 2 gives \(83,072\).

Expanded form: \(80{,}000 + 3{,}000 + 70 + 2\) (the hundreds place is 0, so there is no hundreds term).

\(83,072\) = \(80{,}000 + 3{,}000 + 70 + 2\)

Worksheet problem 17 and after

17 – City populations

Oak Hill starts 89, so it is least. The other three start 98.

Compare the hundreds: Maple Grove has 4, Cedar Falls has 0, Pine Bluff has 5. Greatest first: Pine Bluff (5), Maple Grove (4), Cedar Falls (0).

Pine Bluff \(98,504\), Maple Grove \(98,450\), Cedar Falls \(98,054\), Oak Hill \(89,540\)

18 – Odometer rolls over

One more mile moves the odometer to 100,000.

\(99{,}999 + 1 = 100{,}000\).

The 1 is in the hundred thousands place, so its value is \(100,000\).

Check: \(100,000\) is ten times \(10,000\).

100,000; 100,000

19 – Who is right?

Count places in \(350,260\): 3 hundred thousands, 5 ten thousands, 0 thousands, 2 hundreds, 6 tens, 0 ones.

The 5 is worth \(5 \times 10{,}000 = 50{,}000\), so Noah is correct and Mei is not. Mei used the thousands place by mistake.

Noah is correct; the 5 is worth 50,000.

20 – Stickers by ten

Carton: \(4{,}000 \times 10 = 40{,}000\).

Pallet: \(40{,}000 \times 10 = 400{,}000\).

Word form: four hundred thousand.

400,000; four hundred thousand

Key facts behind this 4th grade place value worksheet answers

Key facts

A digit in any place is worth 10 times the same digit one place to its right.
Places from the right: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions.
Expanded form adds the value of each digit: 4,203 = 4,000 + 200 + 3.
Then, compare numbers from the left, place by place, and use the symbols <, >, or =.
1,000,000 is ten times as much as 100,000.

Common mistakes with this 4th grade place value worksheet answers

Students match the digits but miss the commas or word spelling. Instead, check that your number words and commas follow the key.
Students skip the reasoning in problem 19. Also, the key explains why 5 is worth fifty thousand, and the explanation is part of the answer.
Students compare problem 17 by looking only at the first two digits. Instead, the key compares each place from the left in turn.
Students forget the value in problem 15. The question asks for the value of the digit and the word form, so check for both.

How to use these solutions

Read each answer aloud in words. Then, if it sounds right, the digits and places are probably in order.
Redo each missed problem in a place value chart. Finally, a chart shows which place was misplaced. Repeat this habit on every problem for the best results.
Parents can ask the child to explain why the 6 in 462,159 is worth 60,000 and not just 6.

4th grade place value worksheet answers: frequently asked questions

What is the value of the digit 6 in 462,159?

The 6 is in the ten thousands place, so its value is 60,000. The digit 4 is worth 400,000, and the digit 2 is worth 2,000. Reading each digit by its place gives the full value of the number.

How do you write 52,014 in word form?

Write fifty-two thousand, fourteen. The part before the comma is read as 52 thousand, and the rest is 14. Hyphens join the tens and ones words in numbers like fifty-two. A quick check like this takes only a few seconds and prevents most errors.

How do you know the odometer in problem 18 reads 100,000?

When the odometer shows 99,999 and one more mile is added, the ones roll over and carry into every place. Each 9 becomes 0 and a 1 appears in the hundred thousands place, so it reads 100,000.
