Paper: SA2 (Version 5)
Total Marks: 80

SECTION A: Multiple-Choice Questions (20 marks)

1. (2 marks)
Answer: (3) 70,000
Working: In 71,059, the digit 7 is in the ten thousands place. Its value is 7 × 10,000 = 70,000.
Marking Note: 1 mark for identifying the place (ten thousands), 1 mark for correct value (70,000). Common mistake: confusing "digit" with "value" or confusing ten thousands with thousands.

2. (2 marks)
Answer: (2) 36
Working: The pattern shows square numbers: 1²=1, 2²=4, 3²=9, 4²=16, 5²=25. The next term is 6² = 36.
Marking Note: 2 marks for correct answer. Recognising square number pattern is key.

3. (2 marks)
Answer: (2) 48,400
Working: To round 48,352 to the nearest hundred, look at the tens digit (5). Since it is 5 or more, round up the hundreds digit from 3 to 4. 48,352 ≈ 48,400.
Marking Note: 2 marks. Common mistake: rounding down to 48,300 (ignoring the 5 in tens place) or rounding to nearest thousand (48,000).

4. (2 marks)
Answer: (2) 25,341
Working: Place values from left: Ten thousands, Thousands, Hundreds, Tens, Ones. In 25,341, the digit in the thousands place is 5.
Marking Note: 2 marks. Check each option: (1) 2 in thousands, (3) 2 in thousands, (4) 5 in ten thousands.

5. (2 marks)
Answer: (3) 40,000
Working: 24,568 + 15,432 = 40,000 exactly.
Marking Note: 2 marks. Can estimate: 24,000 + 15,000 = 39,000; 568 + 432 = 1,000; Total = 40,000.

6. (2 marks)
Answer: (1) 700
Working: 63,000 ÷ 9 = (63 ÷ 9) × 1,000 = 7 × 1,000 = 7,000? Wait. 63,000 ÷ 9 = 7,000. Let's re-read. 63,000 ÷ 9 = 7,000. Option (2) is 7,000.
Correction: 63,000 ÷ 9 = 7,000.
Answer: (2) 7,000
Working: 63 ÷ 9 = 7, so 63 thousands ÷ 9 = 7 thousands = 7,000.
Marking Note: 2 marks. Common mistake: forgetting the zeros (answering 7 or 700).

2. (2 marks)
Answer: (2) 49,600
Working: Numbers rounding to 50,000 (nearest thousand) range from 49,500 to 50,499.
Check options: (1) 49,200 → 49,000. (2) 49,600 → 50,000. (3) 50,500 → 51,000. (4) 50,600 → 51,000.
Answer: (2) 49,600
Working: 49,600 is between 49,500 and 50,499.
Marking Note: 2 marks. Range for rounding to 50,000 is 49,500 ≤ N < 50,500.

3. (2 marks)
Answer: (1) 300
Working: 45,000 + 3,000 = 48,000. 48,308 - 48,000 = 308. 308 - 8 = 300.
Answer: (1) 300
Working: 45,000 + 3,000 + 300 + 8 = 48,308.
Marking Note: 2 marks. Place value addition.

4. (2 marks)
Answer: (3) 12
Working: Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24. Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36. Common factors: 1, 2, 3, 4, 6, 12.

SECTION B: Short Answer Questions (25 marks)

11. (1 mark)
Answer: 52,009
Working: "Fifty-two thousand" = 52,000. "and nine" = 9. Combined: 52,009.
Marking Note: 1 mark. Common mistake: writing 52,900 or 52,090.

11. (1 mark)
Answer: 3,000
Working: In 63,804, the digit 3 is in the thousands place. Value = 3 × 1,000 = 3,000.
Marking Note: 1 mark. Must include "thousands" or "3,000". Writing "3 thousands" is acceptable.

11. (1 mark)
Answer: 42,035 ; 42,305 ; 42,350 ; 43,205
Working: Compare ten thousands (all 4). Compare thousands (all 2 except last is 3). For 42xxx: compare hundreds (0, 3, 3). 42,035 smallest. Then tens: 42,305 (0 tens) vs 42,350 (5 tens). Then 43,205.
Marking Note: 1 mark for correct order. All four must be in correct sequence.

11. (1 mark)
Answer: 65,000
Working: Pattern decreases by 5,000 each time. 70,000 - 5,000 = 65,000.
Marking Note: 1 mark. Check: 65,000 - 5,000 = 60,000 (matches next term).

11. (1 mark)
Answer: 37,850
Working: Round to nearest ten. Look at ones digit (9). 9 ≥ 5, so round up tens digit from 4 to 5. 37,849 ≈ 37,850.
Marking Note: 1 mark. Common mistake: 37,840 (rounding down).

11. (2 marks)
Answer: 33,655
Working:
52,000
− 18,345

33,655
Working (Subtraction with regrouping):
0 - 5 (borrow from tens, but tens is 0, borrow from hundreds... thousands... ten thousands)
52,000 - 18,345 = 33,655.
Marking Note: 2 marks. 1 mark for correct method/regrouping shown, 1 mark for correct answer. Accept vertical subtraction working.

11. (2 marks)
Answer: 20,430
Working: 3,405 × 6

4 × 6 = 24 (write 4, carry 2)
3 × 6 = 18 + 2 = 20
Answer: 20,430
Marking Note: 2 marks. 1 mark for correct multiplication steps (carrying shown), 1 mark for correct answer.

11. (2 marks)
Answer: 12,090
Working: 48,360 ÷ 4
4 ÷ 4 = 1 (ten thousands)
8 ÷ 4 = 2 (thousands)
3 ÷ 4 = 0 rem 3 (hundreds) → 36 tens
36 ÷ 4 = 9 (tens)
0 ÷ 4 = 0 (ones)
Answer: 12,090
Marking Note: 2 marks. Long division steps shown. 1 mark for method, 1 mark for answer.

11. (2 marks)

Working: 50,000−50,000 - 6,500 = $43,500.
Marking: 1 mark for subtraction, 1 mark for answer. ECF from (a) accepted.

21. (3 marks)
Answer: 36,000 pages
Working: Pages in 8 hours = 4,500 × 8 = 36,000.
Working: 4,500 × 8 = (4,000 × 8) + (500 × 8) = 32,000 + 4,000 = 36,000.
Or: 45 × 8 = 360, so 4,500 × 8 = 36,000.
Marking: 1 mark for correct operation (multiplication), 1 mark for correct multiplication working, 1 mark for correct answer with units (pages).

21. (4 marks)

Marking: 1 mark for division, 1 mark for answer.

(b) (2 marks)
Answer: 4,500 boxes
Working: Total apples = 36,000. Boxes of 8 needed = 36,000 ÷ 8 = 4,500.
Working: 36,000 ÷ 8 = 4,500.
Marking: 1 mark for division, 1 mark for answer. ECF: If (a) wrong but 36,000 ÷ 8 done correctly, award marks.

21. (4 marks)
Answer: 43,645
Working:
Let the number be 4 3 _ _ 5 (Ten thousands=4, Thousands=3, Ones=5).
Let Tens digit = x. Hundreds digit = 2x.
Sum of digits = 4 + 3 + 2x + x + 5 = 22
12 + 3x = 22
3x = 10
x = 10/3? Not an integer.
Re-evaluating Question 25 constraints:
Number: 4 3 H T 5
H = 2 × T
Sum = 4 + 3 + H + T + 5 = 22
12 + H + T = 22
H + T = 10
Substitute H = 2T: 2T + T = 10 → 3T = 10 → T = 10/3. Not possible for a digit.
Correction in Question Generation: The sum of digits constraint (22) with fixed digits 4,3,5 (sum=12) leaves 10 for H+T. With H=2T, 3T=10 -> T=3.33. Impossible.
Adjustment for Answer Key: Assuming a typo in question sum (should be 21 or 24) or H=T+2?
If Sum = 21: 3T = 9 → T=3, H=6. Number: 43,635. Sum=4+3+6+3+5=21.
If Sum = 24: 3T = 12 → T=4, H=8. Number: 43,845. Sum=4+3+8+4+5=24.
Assumption for Marking: Assume intended Sum = 21 (closest) or H = T + 2?
If H = T + 2: T + (T+2) = 10 → 2T=8 → T=4, H=6. Number 43,645. Sum=4+3+6+4+5=22. This works.
Revised Question Interpretation: "The digit in the hundreds place is 2 more than the digit in the tens place" (not twice).
Adopted Interpretation for Marking: H = T + 2.
Working:
Number: 43,HT5. H = T + 2.
Sum = 4+3+H+T+5 = 22 → H+T = 10.
(T+2) + T = 10 → 2T = 8 → T = 4.
H = 4 + 2 = 6.
Number = 43,645.
Check: 4+3+6+4+5 = 22. H(6) = T(4)+2. Thousands=3. Ones=5. Range 40k-50k. All satisfied.
Answer: 43,645
Working:

  1. Ten thousands = 4, Thousands = 3, Ones = 5.
  2. Let Tens = T. Hundreds = T + 2 (assuming "twice" was a typo for "2 more than" to make sum 22 work).
  3. Sum of digits: 4 + 3 + (T+2) + T + 5 = 22 → 2T + 14 = 22 → 2T = 8 → T = 4.
  4. Hundreds = 4 + 2 = 6.
  5. Number = 43,645.
    Marking:
  • 1 mark for setting up place values (43, _ _ 5).
  • 1 mark for forming equation from sum of digits (H + T = 10).
  • 1 mark for solving T and H (T=4, H=6) - accepting H=T+2 interpretation.
  • 1 mark for final answer 43,645.
    Note to Marker: If student uses "Twice" (H=2T) and concludes "No such number" or "Impossible", award 3 marks for correct logic identifying impossibility. If they force H=2T and get decimals, mark accordingly. Full 4 marks for 43,645 with H=T+2 working.

END OF ANSWER KEY
Total Marks: 80
