All questions

Question 1

Round 365 to the nearest hundred.

  1. 200
  2. 300
  3. 500
  4. 400 (correct answer)
Explanation: The tens digit in 365 is 6, which is 5 or more, so 365 rounds up to 400. Choice A (200) rounds down by two hundreds instead of one. Choice B (300) rounds down instead of up. Choice C (500) rounds up by two hundreds instead of one.

Question 2

Round 6363 to the nearest ten.

  1. 50
  2. 60 (correct answer)
  3. 70
  4. 63
Explanation: This question tests 3rd grade place value and rounding: using place value understanding to round whole numbers to the nearest 10 or 100 (CCSS.3.NBT.1). To round to the nearest ten, look at the ones digit: if it's 0−40-4, round down (keep tens digit); if it's 5−95-9, round up (increase tens digit by 1). To round to the nearest hundred, look at the tens digit: if it's 0−40-4, round down (keep hundreds digit); if it's 5−95-9, round up (increase hundreds digit by 1). The result is always a multiple of 10 or 100. The number 6363 is being rounded to the nearest ten. We look at the ones digit, which is 33. Choice B is correct because the ones digit is 33, which is <5<5, so we round down to 6060. This shows understanding of rounding rules and place value. Choice C represents rounding in the wrong direction. This typically happens because students reverse the rounding rule (thinking 33 rounds up). To help students: Use number lines to show proximity to tens or hundreds. For 6363, mark 6060 and 7070, show 6363 is closer to 6060. Teach the rule as '5 or more, round up the floor; 4 or less, let it rest.' Practice identifying the critical digit: 'To round to nearest ten, circle the ONES digit. If 0−40-4, stay at current ten. If 5−95-9, go to next ten.' Use place value charts to visualize: Ones|Tens|Hundreds. Watch for: Students who round the wrong direction, students who look at wrong digit (tens digit when rounding to nearest ten), students who truncate (47→4047 \to 40 by dropping 7) instead of properly rounding to closest ten, and students who don't recognize multiples of 10 (10,20,30…10, 20, 30\ldots). Connect to real contexts: 'If game had 78 people, we could say 'about 80 people' by rounding.'

Question 3

Round 34 to the nearest ten.

  1. 20
  2. 40
  3. 30 (correct answer)
  4. 50
Explanation: Since 34 is closer to 30 than to 40, it rounds down to 30. Choice A (20) is too far from 34 to be the nearest ten. Choice B (40) rounds up when 34 should round down. Choice D (50) is much too far from 34 to be the nearest ten.

Question 4

Round 6363 to the nearest ten.

  1. 50
  2. 60 (correct answer)
  3. 70
  4. 63
Explanation: 60 is correct because the ones digit in 63 is 3, which is less than 5, so we round down to 60. 50 is incorrect because it rounds to a ten too low. 70 is incorrect because it rounds up instead of down. 63 is incorrect because it repeats the original number instead of rounding it.

Question 5

Round 2727 to the nearest ten.

  1. 20
  2. 30 (correct answer)
  3. 40
  4. 10
Explanation: 30 is correct because the ones digit in 27 is 7, which is 5 or greater, so we round up to 30. 20 is incorrect; that would mean rounding down, which doesn't apply here. 40 is incorrect because it's one ten too high. 10 is incorrect; it's too far below 27 to be the correct rounding.

Question 6

A toy store has 673 action figures. What is 673 rounded to the nearest ten?

  1. 680
  2. 670 (correct answer)
  3. 600
  4. 700
Explanation: 673 is between 670 and 680. Since 673 is closer to 670, it rounds to 670, matching choice B. Choice A rounds up to the wrong nearest ten. Choices C and D are rounded to the nearest hundred instead of the nearest ten.

Question 7

A library has 425425 books on one shelf. What is 425425 rounded to the nearest hundred?

  1. 400400 (correct answer)
  2. 500500
  3. 430430
  4. 420420
Explanation: 425 is between 400 and 500. Since the tens digit is 2, which is less than 5, round down to 400. Choice B, 500, comes from rounding up instead of down. Choice C, 430, rounds to the nearest ten instead of the nearest hundred. Choice D, 420, is also a nearest-ten value, not the nearest hundred.

Question 8

Round 730 to the nearest hundred.

  1. 900
  2. 700 (correct answer)
  3. 600
  4. 800
Explanation: Since 730 is closer to 700 than to 800, it rounds down to 700. Choice A (900) is much too far from 730 to be the nearest hundred. Choice C (600) is too far below 730 to be the nearest hundred. Choice D (800) rounds up when 730 should round down.

Question 9

Round 47 to the nearest ten.

  1. 50 (correct answer)
  2. 70
  3. 40
  4. 60
Explanation: Since 47 is closer to 50 than to 40, it rounds up to 50. Choice B (70) is much too far from 47 to be the nearest ten. Choice C (40) rounds down when 47 should round up. Choice D (60) is also too far from 47 to be the nearest ten.

Question 10

Round 450 to the nearest hundred.

  1. 500 (correct answer)
  2. 600
  3. 400
  4. 300
Explanation: The tens digit in 450 is 5, so it rounds up to 500. Choice B (600) rounds up by two hundreds instead of one. Choice C (400) rounds down instead of up. Choice D (300) rounds down by two hundreds instead of up by one.

Question 11

Round 3838 to the nearest ten.

  1. 30
  2. 40 (correct answer)
  3. 50
  4. 20
Explanation: 40 is correct because the ones digit in 38 is 8, which is 5 or greater, so we round up to 40. 30 is incorrect because it rounds down instead of up. 50 is incorrect because it rounds to a ten too high. 20 is incorrect because it does not match rounding 38 to the nearest ten.

Question 12

Round 237237 to the nearest hundred.

  1. 500
  2. 300
  3. 200 (correct answer)
  4. 400
Explanation: 200 is correct because 237 is closer to 200 than to 300 when rounding to the nearest hundred. 500 is incorrect; it isn't a plausible rounding of 237. 300 is incorrect because 237 is below the midpoint of 250, so it rounds down. 400 is incorrect; it's too far from 237 to be correct.

Question 13

Round 465 to the nearest hundred.

  1. 600
  2. 300
  3. 500 (correct answer)
  4. 400
Explanation: The correct answer is C) 500, since 465 is closer to 500 than to 400 when rounding to the nearest hundred (65 is more than halfway from 400 to 500). Choice A (600) rounds up too far, by two hundreds instead of one. Choice B (300) rounds in the wrong direction entirely. Choice D (400) is the truncation/round-down error, rounding to the lower hundred instead of the nearer one.

Question 14

Round 237237 to the nearest hundred.

  1. 200 (correct answer)
  2. 500
  3. 400
  4. 300
Explanation: This question tests 3rd grade place value and rounding: using place value understanding to round whole numbers to the nearest 10 or 100 (CCSS.3.NBT.1). To round to the nearest ten, look at the ones digit: if it's 0-4, round down (keep tens digit); if it's 5-9, round up (increase tens digit by 1). To round to the nearest hundred, look at the tens digit: if it's 0-4, round down (keep hundreds digit); if it's 5-9, round up (increase hundreds digit by 1). The result is always a multiple of 10 or 100. The number 237 is being rounded to the nearest hundred. We look at the tens digit, which is 3. Choice A is correct because the tens digit is 3, which is <5, so we round down to 200. This shows understanding of rounding rules and place value. Choice B represents rounding in the wrong direction. This typically happens because students reverse the rounding rule (thinking 3 rounds up). To help students: Use number lines to show proximity to tens or hundreds. For 237, mark 200 and 300, show 237 is closer to 200. Teach the rule as '5 or more, round up the floor; 4 or less, let it rest.' Practice identifying the critical digit: 'To round to nearest hundred, circle the TENS digit. If 0-4, stay at current hundred. If 5-9, go to next hundred.' Use place value charts to visualize: Ones|Tens|Hundreds. Watch for: Students who round the wrong direction, students who look at wrong digit (ones digit when rounding to nearest hundred), students who truncate (547→500 by dropping), and students who don't recognize multiples of 100 (100,200,300...). Connect to real contexts: 'If game had 78 people, we could say 'about 80 people' by rounding.'

Question 15

Round 340 to the nearest hundred.

  1. 400
  2. 200
  3. 300 (correct answer)
  4. 500
Explanation: 340 is between 300 and 400. Since 340 is closer to 300 than to 400, it rounds to 300, matching choice C. Choice A rounds up instead of down. Choices B and D use hundreds that are not the two closest to 340.

Question 16

Jamal counted 74 birds. Round this number to the nearest ten.

  1. 60
  2. 90
  3. 70 (correct answer)
  4. 80
Explanation: 70 is correct because the ones digit in 74 is 4, which is less than 5, so we round down to 70. 60 is incorrect because it rounds to a ten too low. 90 is incorrect because it rounds up too far. 80 is incorrect because it rounds up instead of down.

Question 17

Round 782782 to the nearest hundred.

  1. 800 (correct answer)
  2. 780
  3. 900
  4. 700
Explanation: The tens digit in 782 is 8, which is 5 or more, so round up to 800. Choice B, 780, rounds to the nearest ten instead of the nearest hundred. Choice C, 900, rounds up too far past the correct hundred. Choice D, 700, rounds down instead of up.

Question 18

A store has 63 toys. What is 63 rounded to the nearest ten?

  1. 70
  2. 80
  3. 60 (correct answer)
  4. 50
Explanation: Since 63 is closer to 60 than to 70, it rounds down to 60. Choice A (70) rounds up incorrectly. Choice B (80) is too far from 63 to be the nearest ten. Choice D (50) is also too far from 63 to be the nearest ten.

Question 19

What is 38 rounded to the nearest ten?

  1. 40 (correct answer)
  2. 50
  3. 30
  4. 20
Explanation: 38 is closer to 40 than to 30, and since the ones digit (8) is 5 or greater, we round up to 40, making Choice A correct. Choice B (50) rounds to the next ten beyond 40. Choice C (30) rounds down instead of up. Choice D (20) is not the nearest ten to 38 at all.

Question 20

Round 4444 to the nearest ten.

  1. 40 (correct answer)
  2. 50
  3. 30
  4. 60
Explanation: The ones digit in 44 is 4, which is less than 5, so round down to 40. Choice B, 50, comes from rounding up instead of down. Choice C, 30, is too small to be the nearest ten. Choice D, 60, is not close to 44 at all.
