TuitionGoWhere Practice Paper - Mathematics Primary 4
Answer Key — Practice Paper 1 (Version 1 of 5)
Subject: Mathematics | Level: Primary 4 | Topic: Whole Numbers (up to 100,000)
Section A: Place Value and Number Sense (10 marks)
1. Write the following number in numerals. (2 marks)
Seventy-two thousand, four hundred and six.
Answer: 72,406
Working:
- Seventy-two thousand = 72,000
- Four hundred = 400
- Six = 6
- Combined: 72,000 + 400 + 6 = 72,406
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student writes 72,460 or 72,046 (digit transposition error — partial credit for understanding place value structure).
- Common mistake: Writing "72,46" or "7246" (omitting the thousands place zero).
2. In the number 63,815, what does the digit 8 stand for? (2 marks)
Answer: 800 (or "eight hundred")
Working:
- The number 63,815 has the following place values:
- 6 → ten thousands place → 60,000
- 3 → thousands place → 3,000
- 8 → hundreds place → 800
- 1 → tens place → 10
- 5 → ones place → 5
- The digit 8 is in the hundreds place, so it stands for 800.
Marking Notes:
- 2 marks for "800" or "eight hundred."
- 1 mark if the student writes "8" or "hundreds" without the value.
- Common mistake: Writing "80" (confusing hundreds with tens place).
3. Arrange the following numbers in order, starting with the smallest. (2 marks)
45,230 | 45,032 | 45,320 | 45,203
Answer: 45,032, 45,203, 45,230, 45,320
Working:
- All numbers have the same ten thousands digit (4) and thousands digit (5).
- Compare the hundreds digits: 0, 2, 2, 3
- 45,032 has 0 hundreds → smallest
- Between 45,203 and 45,230: compare tens digits → 0 < 3, so 45,203 < 45,230
- 45,320 has 3 hundreds → largest
- Order: 45,032 < 45,203 < 45,230 < 45,320
Marking Notes:
- 2 marks for all four numbers in correct order.
- 1 mark if only one or two numbers are out of place but the general strategy is correct.
- Common mistake: Comparing only the last two or three digits instead of working left to right.
4. What is the value of the digit 7 in the number 78,429? (2 marks)
Answer: 70,000 (or "seventy thousand")
Working:
- The number 78,429:
- 7 → ten thousands place → 70,000
- 8 → thousands place → 8,000
- 4 → hundreds place → 400
- 2 → tens place → 20
- 9 → ones place → 9
- The digit 7 is in the ten thousands place, so its value is 70,000.
Marking Notes:
- 2 marks for "70,000" or "seventy thousand."
- 1 mark if the student writes "7" or "ten thousands" without the full value.
- Common mistake: Writing "7,000" (confusing ten thousands with thousands).
5. Write the following number in words. (2 marks)
91,053
Answer: Ninety-one thousand and fifty-three
Working:
- 91,053 = 91,000 + 53
- 91,000 in words = "ninety-one thousand"
- 53 in words = "fifty-three"
- Combined: "Ninety-one thousand and fifty-three"
Marking Notes:
- 2 marks for correct answer.
- 1 mark for minor spelling errors (e.g., "fourty" instead of "forty" — though not applicable here) or if the student writes "ninety-one thousand fifty-three" (missing "and" — acceptable in some conventions but "and" is preferred in Singapore syllabus).
- Common mistake: Writing "nine thousand one thousand and fifty-three" or "ninety-one thousand and five hundred three."
Section B: Rounding Numbers (10 marks)
6. Round 34,678 to the nearest hundred. (2 marks)
Answer: 34,700
Working:
- To round to the nearest hundred, look at the tens digit.
- 34,678: the tens digit is 7.
- Since 7 ≥ 5, round up the hundreds digit from 6 to 7.
- Replace tens and ones digits with zeros.
- 34,678 ≈ 34,700
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student rounds to 34,600 (incorrectly rounding down).
- Common mistake: Rounding to the nearest thousand instead (35,000).
7. Round 58,492 to the nearest thousand. (2 marks)
Answer: 58,000
Working:
- To round to the nearest thousand, look at the hundreds digit.
- 58,492: the hundreds digit is 4.
- Since 4 < 5, round down — keep the thousands digit as 8.
- Replace hundreds, tens, and ones digits with zeros.
- 58,492 ≈ 58,000
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student writes 59,000 (incorrectly rounding up).
- Common mistake: Looking at the tens digit (9) instead of the hundreds digit (4).
8. A number rounded to the nearest ten is 46,250. What is the smallest possible value of this number? (2 marks)
Answer: 46,245
Working:
- When rounding to the nearest ten, numbers from 46,245 to 46,254 round to 46,250.
- The smallest number that rounds to 46,250 is 46,245.
- Reasoning: The tens digit is 5, and the ones digit must be 5 or more to round up to 46,250. The smallest such number is when the ones digit is exactly 5.
- 46,245 ≈ 46,250 (nearest ten)
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student writes 46,250 (not understanding that the original number must be different).
- Common mistake: Writing 46,244 (which would round to 46,240, not 46,250).
9. Round 72,505 to the nearest thousand. (2 marks)
Answer: 73,000
Working:
- To round to the nearest thousand, look at the hundreds digit.
- 72,505: the hundreds digit is 5.
- Since 5 ≥ 5, round up the thousands digit from 2 to 3.
- Replace hundreds, tens, and ones digits with zeros.
- 72,505 ≈ 73,000
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student writes 72,000 (incorrectly rounding down when the hundreds digit is exactly 5).
- Common mistake: Rounding down when the digit is 5 — students sometimes forget that 5 rounds up.
10. A number rounded to the nearest hundred is 83,600. What is the largest possible value of this number? (2 marks)
Answer: 83,649
Working:
- When rounding to the nearest hundred, numbers from 83,550 to 83,649 round to 83,600.
- The largest number that rounds to 83,600 is 83,649.
- Reasoning: The hundreds digit is 6. For the number to round down to 83,600, the tens digit must be less than 5. The largest tens digit less than 5 is 4, and the largest ones digit is 9.
- 83,649 ≈ 83,600 (nearest hundred)
Marking Notes:
- 2 marks for correct answer.
- 1 mark if the student writes 83,650 (which would round to 83,700, not 83,600).
- Common mistake: Writing 83,699 (which would round to 83,700).
