SA2 Version 2 - Answer Key and Marking Scheme

Total Marks: 60

SECTION A: Multiple-Choice Questions (15 marks)

1. Answer: (2) tens

Marks: 1
Explanation: In the number 8 472, the digits from right to left are: 2 (ones), 7 (tens), 4 (hundreds), 8 (thousands). The digit 7 is in the tens place.
Common mistake: Confusing "place" with "value". The value of 7 is 70, but its place is tens.

2. Answer: (4) 5 000

Marks: 1
Explanation: In 5 309, the digit 5 is in the thousands place. Its value is 5 × 1 000 = 5 000.
Key concept: Value of digit = digit × place value.

3. Answer: (3) 3 284

Marks: 1
Explanation: Compare thousands (all 3), then hundreds: 2 < 4 < 8. So 3 284 is the smallest.
Method: Compare digits from left to right (thousands → hundreds → tens → ones).

4. Answer: (1) 6 700

Marks: 1
Explanation: To round to the nearest hundred, look at the tens digit (4). Since 4 < 5, round down. 6 748 → 6 700.
Rule: If tens digit is 0-4, round down; if 5-9, round up.

5. Answer: (1) 4 683

Marks: 1
Explanation: 4 000 + 600 + 80 + 3 = 4 683. Add each place value.

6. Answer: (3) 2 600

Marks: 1
Explanation: Pattern increases by 50 each time: 2 450, 2 500, 2 550, 2 600, 2 650.
Method: Find the difference between consecutive terms (2 500 - 2 450 = 50).

7. Answer: (2) 9 027

Marks: 1
Working:

  7 345
+ 1 682
-------
  9 027

Ones: 5+2=7, Tens: 4+8=12 (carry 1), Hundreds: 3+6+1=10 (carry 1), Thousands: 7+1+1=9.

8. Answer: (2) 5 533

Marks: 1
Working:

  8 000
- 2 467
-------
  5 533

Regrouping needed: 8 000 = 7 999 + 1, then subtract.

9. Answer: (2) 8 + 8 + 8 + 8 + 8 + 8

Marks: 1
Explanation: 6 × 8 means 6 groups of 8, which is 8 added 6 times. Option (1) shows 8 groups of 6 (8 × 6). Multiplication is commutative but the representation must match.

10. Answer: (2) 7

Marks: 1
Explanation: 56 ÷ 8 = 7 because 8 × 7 = 56. Use multiplication fact to check division.

11. Answer: (2) 52

Marks: 1
Working: Number = (Divisor × Quotient) + Remainder = (6 × 8) + 4 = 48 + 4 = 52.
Formula: Dividend = Divisor × Quotient + Remainder.

12. Answer: (1) 2 375

Marks: 1
Working: Children = Total - Adults = 4 250 - 1 875 = 2 375.
Check: 2 375 + 1 875 = 4 250 ✓

13. Answer: (3) 240

Marks: 1
Working: Sweets per box = 6 × 8 = 48. Sweets in 5 boxes = 48 × 5 = 240.
Alternative: 6 × 8 × 5 = 240.

14. Answer: (1) $977

Marks: 1
Working: Total spent = $2 345 +$ 1 678 = $4 023. Money left =$ 5 000 - $4 023 =$ 977.

15. Answer: (2) 3 458

Marks: 1
Explanation: Even numbers end in 0, 2, 4, 6, 8. Between 3 450 and 3 470: 3 452, 3 454, 3 456, 3 458, 3 460, 3 462, 3 464, 3 466, 3 468. Only 3 458 is in the options.

SECTION B: Short-Answer Questions (25 marks)

16. Answer: Six thousand and forty-five

Marks: 1
Explanation: 6 045 = 6 thousands + 0 hundreds + 4 tens + 5 ones. "And" is used before the last two digits when there are zero hundreds.
Note: Do not write "six thousand forty-five" (missing "and") or "six thousand zero hundred forty-five".

17. Answer: 200 / two hundred

Marks: 1
Explanation: In 9 207, the digit 2 is in the hundreds place. Its value is 2 × 100 = 200.
Key distinction: "What does the digit stand for?" asks for value, not place.

18. Answer: 5 832, 5 382, 5 328, 5 283

Marks: 1
Explanation: All have 5 thousands. Compare hundreds: 8 > 3 > 2. For 5 382 and 5 328 (both 3 hundreds), compare tens: 8 > 2.
Order: 5 832 (8 hundreds) > 5 382 (3 hundreds, 8 tens) > 5 328 (3 hundreds, 2 tens) > 5 283 (2 hundreds).

19. Answer: 4 570

Marks: 1
Explanation: Round to nearest ten. Look at ones digit (7). Since 7 ≥ 5, round up. 4 567 → 4 570.
Rule: Ones digit 0-4 round down, 5-9 round up.

20. Answer: 6 600, 6 200

Marks: 2
Working: Pattern decreases by 200 each time.
7 200 - 200 = 7 000
7 000 - 200 = 6 800
6 800 - 200 = 6 600
6 600 - 200 = 6 400
6 400 - 200 = 6 200
Mark breakdown: 1 mark for each correct missing number.

21. Answer: 6 245

Mark breakdown: 1 mark for finding total apples, 1 mark for correct final answer.

29. Answer: 5 255

Marks: 2

Mark breakdown: 1 mark for (a) correct subtraction, 1 mark for (b) correct addition, 1 mark for both answers correct with units, 1 mark for clear working.

34. Answer: 98 trays

Marks: 4
Working:
Step 1: Eggs sold = 1 875 + 2 146 = 4 021
Step 2: Eggs remaining = 5 000 - 4 021 = 979
Step 3: Trays needed = 979 ÷ 10 = 97 remainder 9 → 98 trays (need 1 more tray for remaining 9 eggs)
Important: Since eggs must be packed into trays of 10, 979 eggs need 98 trays (97 full trays + 1 tray for the last 9 eggs).
Mark breakdown: 1 mark for total eggs sold, 1 mark for eggs remaining, 1 mark for division by 10, 1 mark for correct interpretation of remainder (98 trays not 97).

35. Answer: 144 pages

Marks: 4
Working:
Step 1: Pages read in 8 days = 15 × 8 = 120 pages
Step 2: Pages left = 324 - 120 = 204 pages
Wait, let me recalculate: 324 - 120 = 204. But the question asks "how many more pages does she need to read to finish the book?"
Answer: 204 pages.
Let me verify: 15 × 8 = 120. 324 - 120 = 204. Yes.
Mark breakdown: 1 mark for pages read (15 × 8), 1 mark for correct subtraction, 1 mark for correct final answer with unit (pages), 1 mark for clear step-by-step working.

MARKING NOTES FOR TEACHERS

Section A (MCQ): Award 1 mark per correct answer. No half marks.
Section B (Short Answer):
- For 2-mark questions: 1 mark for correct method/working, 1 mark for correct answer.
- Accept alternative valid methods (e.g., mental math shown clearly).
- Deduct 1 mark for missing units where applicable (e.g., $, pages, trays).
Section C (Long Answer):
- Marks awarded for each logical step.
- Method marks given even if final answer is wrong due to arithmetic error.
- For Q34, the remainder interpretation is critical: 979 ÷ 10 = 97 R 9 → 98 trays. Award full 4 marks only if student correctly identifies 98 trays.
- For Q35, ensure students calculate pages read first (15 × 8 = 120), then subtract from total.

COMMON STUDENT ERRORS TO WATCH

Place value: Confusing "digit in the hundreds place" with "value of the digit in the hundreds place".
Rounding: Rounding to wrong place value (e.g., rounding to nearest ten when asked for hundred).
Subtraction with zeros: Errors in regrouping across zeros (e.g., 5 000 - 1 847).
Division with remainder: Forgetting to add remainder back when finding original number.
Multi-step problems: Solving only the first step (e.g., finding boxes but not money in Q32).
Remainder interpretation: Giving 97 trays instead of 98 in Q34 (not accounting for the last partial tray).
