All questions

Question 1

Round $45,678$ to the nearest thousand.

460,000
45,000
45,700
46,000 (correct answer)

Explanation: Choice D is correct because when rounding 45,678 to the nearest thousand, the hundreds digit (6) rounds the thousands digit up from 45,000 to 46,000. Choice A is incorrect because it rounds to the nearest ten-thousand instead of the nearest thousand. Choice B is incorrect because it rounds down instead of up, even though the hundreds digit calls for rounding up. Choice C is incorrect because it rounds to the nearest hundred, not the nearest thousand.

Question 2

What is 8,456 rounded to the nearest hundred?

8,500 (correct answer)
8,000
8,460
8,400

Explanation: Choice A is correct because the digit in the tens place (5) rounds the hundreds digit up, making 8,456 round to 8,500. Choice B is incorrect because it rounds to the nearest thousand instead of the nearest hundred. Choice C is incorrect because it only changes the tens and ones digits without rounding to the nearest hundred. Choice D is incorrect because it rounds down instead of up.

Question 3

Round 28,345 to the nearest ten thousand.

300,000
30,000 (correct answer)
28,000
20,000

Explanation: This question tests 4th grade ability to use place value understanding to round multi-digit whole numbers to any place (CCSS.4.NBT.3). Rounding simplifies a number by changing it to the nearest value at a specified place. The process: (1) Identify the rounding place, (2) Look at the digit immediately to the right, (3) If that digit is 0-4, round DOWN (keep the rounding digit the same), if it's 5-9, round UP (increase the rounding digit by 1), (4) All digits to the right of the rounding place become 0. To round 28,345 to the nearest ten thousand, we look at the 2 in the ten thousands place and check the 8 in the thousands place to determine whether to round up. Choice C is correct because the digit to the right of the ten thousands place is 8, which is ≥5 so we round up, changing the ten thousands from 2 to 3 and making all digits to the right 0, giving us 30,000. This demonstrates correct application of rounding rules and place value understanding. Choice B represents rounding to the nearest thousand instead of ten thousand, which happens when students don't identify the correct rounding place. To help students: Use place value charts to identify rounding place and decision digit clearly. Teach the 'neighbor rule'—look at the neighbor to the right (0-4 = stay, 5-9 = go up). Use number lines to show which benchmark (20,000 or 30,000) a number is closer to. Emphasize that ALL digits to the right become 0 (28,345 rounded to nearest ten thousand is 30,000, not 28,345). Practice with benchmark numbers: 25,000 is exactly halfway between 20,000 and 30,000—by convention we round up to 30,000. Remind students to check their answer makes sense (should be close to original). Watch for: rounding to wrong place, rounding wrong direction (up when should be down), truncating (chopping off) instead of rounding, and forgetting to add all the necessary zeros.

Question 4

Round 24,678 to the nearest thousand.

250,000
24,700
25,000 (correct answer)
24,000

Explanation: To round 24,678 to the nearest thousand, look at the hundreds digit, which is 6, so the number rounds up to 25,000, making Choice C correct. Choice A, 250,000, is ten times too large, as if an extra zero were added by mistake. Choice B, 24,700, rounds to the nearest hundred instead of the nearest thousand. Choice D, 24,000, rounds down even though the hundreds digit of 6 means the number should round up.

Question 5

Keisha rounded 9,876 to the nearest thousand. What is the result?

9,900
9,000
10,000 (correct answer)
100,000

Explanation: This question tests 4th grade ability to use place value understanding to round multi-digit whole numbers to any place (CCSS.4.NBT.3). Rounding simplifies a number by changing it to the nearest value at a specified place. The process: (1) Identify the rounding place, (2) Look at the digit immediately to the right, (3) If that digit is 0-4, round DOWN (keep the rounding digit the same), if it's 5-9, round UP (increase the rounding digit by 1), (4) All digits to the right of the rounding place become 0. To round 9,876 to the nearest thousand, we look at the 9 in the thousands place and check the 8 in the hundreds place to determine whether to round up. Choice C is correct because the digit to the right of the thousands place is 8, which is ≥5 so we round up, changing the thousands from 9 to 10 and making all digits to the right 0, giving us 10,000. This demonstrates correct application of rounding rules and place value understanding. Choice B represents rounding to the nearest hundred instead of thousand, which happens when students don't identify the correct rounding place. To help students: Use place value charts to identify rounding place and decision digit clearly. Teach the 'neighbor rule'—look at the neighbor to the right (0-4 = stay, 5-9 = go up). Use number lines to show which benchmark (9,000 or 10,000) a number is closer to. Emphasize that ALL digits to the right become 0 (9,876 rounded to nearest thousand is 10,000, not 9,876). Practice with benchmark numbers: 9,500 is exactly halfway between 9,000 and 10,000—by convention we round up to 10,000. Remind students to check their answer makes sense (should be close to original). Watch for: rounding to wrong place, rounding wrong direction (up when should be down), truncating (chopping off) instead of rounding, and forgetting to add all the necessary zeros.

Question 6

Round 9,876 to the nearest thousand.

9,900
9,000
100,000
10,000 (correct answer)

Choice C is correct because the digit to the right of the thousands place is 8, which is ≥5 so we round up, changing the thousands from 9 to 10 and making all digits to the right 0, giving us 10,000. This demonstrates correct application of rounding rules and place value understanding. Choice A represents rounding down incorrectly, which happens when students misapply the 0-4 down, 5-9 up rule. To help students: Use place value charts to identify rounding place and decision digit clearly. Teach the 'neighbor rule'—look at the neighbor to the right (0-4 = stay, 5-9 = go up). Use number lines to show which benchmark (9,000 or 10,000) a number is closer to. Emphasize that ALL digits to the right become 0 (9,876 rounded to nearest thousand is 10,000, not 10,876). Practice with benchmark numbers: 9,500 is exactly halfway between 9,000 and 10,000—by convention we round up to 10,000. Remind students to check their answer makes sense (should be close to original). Watch for: rounding to wrong place, rounding wrong direction (up when should be down), truncating (chopping off) instead of rounding, and forgetting to add all the necessary zeros.

Question 7

Round 24,678 to the nearest thousand.

24,700
250,000
24,000
25,000 (correct answer)

Explanation: This question tests 4th grade ability to use place value understanding to round multi-digit whole numbers to any place (CCSS.4.NBT.3). Rounding simplifies a number by changing it to the nearest value at a specified place. The process: (1) Identify the rounding place, (2) Look at the digit immediately to the right, (3) If that digit is 0-4, round DOWN (keep the rounding digit the same), if it's 5-9, round UP (increase the rounding digit by 1), (4) All digits to the right of the rounding place become 0. To round 24,678 to the nearest thousand, we look at the 4 in the thousands place and check the 6 in the hundreds place to determine whether to round up. Choice C is correct because the digit to the right of the thousands place is 6, which is ≥5 so we round up, changing the thousands from 4 to 5 and making all digits to the right 0, giving us 25,000. This demonstrates correct application of rounding rules and place value understanding. Choice B represents rounding down incorrectly, which happens when students misapply the 0-4 down, 5-9 up rule. To help students: Use place value charts to identify rounding place and decision digit clearly. Teach the 'neighbor rule'—look at the neighbor to the right (0-4 = stay, 5-9 = go up). Use number lines to show which benchmark (24,000 or 25,000) a number is closer to. Emphasize that ALL digits to the right become 0 (24,678 rounded to nearest thousand is 25,000, not 25,678). Practice with benchmark numbers: 24,500 is exactly halfway between 24,000 and 25,000—by convention we round up to 25,000. Remind students to check their answer makes sense (should be close to original). Watch for: rounding to wrong place, rounding wrong direction (up when should be down), truncating (chopping off) instead of rounding, and forgetting to add all the necessary zeros.

Question 8

A city has 127,456 people. Round to the nearest ten thousand to estimate the population.

120,000
130,000 (correct answer)
1,270,000
127,000

Explanation: The correct answer is 130,000, because the digit in the thousands place is 7, which rounds the ten-thousands place up from 120,000 to 130,000. Choice A, 120,000, rounds down instead of up, ignoring that the thousands digit is 5 or greater. Choice C, 1,270,000, mistakenly adds an extra place value, making the number ten times too large. Choice D, 127,000, rounds to the nearest thousand instead of the nearest ten thousand.

Question 9

Emma rounds a mystery number to the nearest ten and gets $3,490$ . She rounds the same number to the nearest hundred and gets $3,500$ . Which of these could be Emma's mystery number?

$3,485$
$3,504$
$3,496$
$3,493$ (correct answer)

Explanation: When you encounter rounding problems with two different place values, you need to find a number that satisfies both rounding conditions simultaneously. Think about the range of numbers that would round to each given value. For a number to round to

3,490

when rounded to the nearest ten, it must be between

3,485

and

3,494

(since

3,485

rounds up to

3,490

, while

3,495

would round up to

3,500

). For the same number to round to

3,500

when rounded to the nearest hundred, it must be between

3,450

and

3,549

. The mystery number must fall in both ranges, so it's between

3,485

and

3,494

. Only choice D)

3,493

fits this range. Let's verify:

3,493

rounds to

3,490

(nearest ten) and

3,500

(nearest hundred) ✓ Choice A)

3,485

rounds to

3,490

for the nearest ten, but rounds to

3,500

for the nearest hundred, which seems right at first glance. However,

3,485

is exactly at the boundary and would round to

3,490

for tens, but the hundreds rounding works. Choice B)

3,504

rounds to

3,500

for both tens and hundreds, not

3,490

for tens. Choice C)

3,496

rounds to

3,500

for tens (not

3,490

) and

3,500

for hundreds. Study tip: When solving two-condition rounding problems, find the overlap between the two ranges. Draw number lines if it helps visualize which numbers satisfy both conditions.

Question 10

To the nearest thousand, about how many books are in a library with 24,678 books?

24,700
240,000
25,000 (correct answer)
24,000

Explanation: Since the hundreds digit in 24,678 is 6, which is 5 or greater, the number rounds up to 25,000, making Choice C correct. Choice A, 24,700, rounds to the nearest hundred instead of the nearest thousand. Choice B, 240,000, has an extra zero, as if the number were rounded to the nearest ten thousand instead. Choice D, 24,000, would be correct only if the hundreds digit were less than 5, but it is 6. Looking at the hundreds digit tells you whether to round the thousands place up or keep it the same.

Question 11

Round 45,678 to the nearest thousand.

46,000 (correct answer)
45,000
45,700
460,000

Explanation: Since the hundreds digit in 45,678 is 6, which is 5 or greater, the number rounds up to 46,000, making Choice A correct. Choice B, 45,000, would be correct only if the hundreds digit were less than 5, but it is not. Choice C, 45,700, rounds to the nearest hundred instead of the nearest thousand. Choice D, 460,000, has an extra zero, as if the number were rounded to the nearest ten thousand instead. Looking at the hundreds digit tells you whether to round the thousands place up or keep it the same.

Question 12

Round $347$ to the nearest ten.

3,500
350 (correct answer)
340
347

Explanation: This question tests 4th grade ability to use place value understanding to round multi-digit whole numbers to any place (CCSS.4.NBT.3). Rounding simplifies a number by changing it to the nearest value at a specified place. The process: (1) Identify the rounding place, (2) Look at the digit immediately to the right, (3) If that digit is 0-4, round DOWN (keep the rounding digit the same), if it's 5-9, round UP (increase the rounding digit by 1), (4) All digits to the right of the rounding place become 0. To round 347 to the nearest ten, we look at the 4 in the tens place and check the 7 in the ones place to determine whether to round up. Choice B is correct because the digit to the right of the tens is 7, which is ≥ 5 so we round UP, changing the tens from 4 to 5 and making all digits to the right 0, giving us 350. This demonstrates correct application of rounding rules and place value understanding. Choice A represents rounding down incorrectly, which happens when students misapply the 0-4 down, 5-9 up rule. To help students, use place value charts to identify the rounding place and decision digit clearly, and teach the 'neighbor rule'—look at the neighbor to the right (0-4 = stay, 5-9 = go up). Use number lines to show which benchmark the number is closer to, and emphasize adding necessary zeros when rounding smaller numbers.

Question 13

Keisha drove 3,456 miles on a road trip. Round 3,456 to the nearest hundred.

3,500 (correct answer)
3,460
35,000
3,400

Explanation: To round 3,456 to the nearest hundred, look at the tens digit, which is 5, so the number rounds up to 3,500, making Choice A correct. Choice B, 3,460, rounds to the nearest ten instead of the nearest hundred. Choice C, 35,000, is ten times too large, as if an extra zero were added. Choice D, 3,400, rounds down even though the tens digit of 5 means the number should round up.

Question 14

A store manager rounds a four-digit number of the form 9,_67, where the blank is an unknown hundreds digit, to the nearest hundred and gets 9,600. Later, she rounds the same number to the nearest thousand and gets 10,000. What digit must be in the hundreds place?

$5$ (correct answer)
$6$
$7$
$8$

Explanation: With a hundreds digit of 5, the number is 9,567; rounding to the nearest hundred looks at the tens digit (6), which rounds up to 9,600, and rounding to the nearest thousand looks at the hundreds digit (5), which rounds up to 10,000. Choice B would round to 9,700 for the nearest hundred, which doesn't match the given result. Choice C would round to 9,800 for the nearest hundred, which doesn't match either. Choice D would round to 9,900 for the nearest hundred, which also doesn't match. Choice A is the only digit that produces both given rounded values.

Question 15

Carlos writes the number $6,\square 48$ where $\square$ represents a missing digit. If this four-digit number rounds to $6,000$ when rounded to the nearest thousand, what is the largest possible value for the missing digit?

$3$
$4$ (correct answer)
$5$
$6$

Explanation: For

6,\square 48

to round down to

6,000

, the hundreds digit must make the number less than

6,500

. The largest digit that works is

4

, giving

6,448

, which rounds down to

6,000

. Choice A gives a smaller valid digit but not the largest. Choice C gives

6,548

, which rounds up to

7,000

. Choice D gives

6,648

, which also rounds up to

7,000

Question 16

A library has $8,429$ books. The librarian rounds this number to different place values for different reports. What is the difference between the number rounded to the nearest thousand and the number rounded to the nearest hundred?

$371$
$571$
$429$
$400$ (correct answer)

Explanation: The correct answer is 400, because 8,429 rounds to 8,000 at the nearest thousand and to 8,400 at the nearest hundred, and the difference between those two is 400. Choice A, 371, does not match either rounding calculation and reflects an arithmetic error. Choice B, 571, similarly does not correspond to a correct rounding step. Choice C, 429, mistakes the original number's last three digits for the actual difference between the rounded values.

Question 17

Keisha rounded $9,876$ to the nearest thousand. What is the result?

90,000
9,900
9,000
10,000 (correct answer)

Explanation: Since 9,876 is closer to 10,000 than to 9,000, it rounds up to 10,000, making Choice D correct. Choice A, 90,000, has an extra zero, as if the number were rounded to the nearest ten thousand instead of the nearest thousand. Choice B, 9,900, comes from rounding to the nearest hundred instead of the nearest thousand. Choice C, 9,000, would be correct only if the hundreds digit were less than 5, but since it is 8, the number rounds up instead. Looking at the hundreds digit tells you which thousand the number is closer to.

Question 18

Round 45,678 to the nearest thousand.

460,000
45,700
46,000 (correct answer)
45,000

Explanation: The hundreds digit in 45,678 is 6, which is 5 or greater, so the thousands digit rounds up, giving 46,000. Choice A shifts the digits by an extra place, making the value ten times too large. Choice B rounds to the nearest hundred instead of the nearest thousand. Choice D rounds down instead of up, ignoring that the hundreds digit calls for rounding up. Choice C correctly rounds 45,678 to the nearest thousand.

Question 19

Look at the number line. Point $P$ represents the number $7,284$ . If this number is rounded to the nearest thousand, which point on the number line best represents the rounded number?

Point $A$
Point $B$ (correct answer)
Point $C$
Point $D$

Explanation:

7,284

rounded to the nearest thousand is

7,000

(since

284 < 500

). Point B represents

7,000

on the number line. Point A represents

6,000

. Point C represents

7,500

. Point D represents

8,000

Question 20

Round $28,345$ to the nearest ten thousand.

30,000 (correct answer)
28,000
20,000
300,000

Explanation: The digit in the thousands place of 28,345 is 8, which is 5 or greater, so the number rounds up to 30,000, making Choice A correct. Choice B, 28,000, rounds to the nearest thousand instead of the nearest ten thousand. Choice C, 20,000, would be correct only if the thousands digit were less than 5, but it is 8. Choice D, 300,000, has an extra zero, as if the number were rounded to the nearest hundred thousand instead. Looking at the digit in the thousands place tells you whether to round the ten thousands place up or keep it the same.
