SA2 Practice Paper 2 (Version 2) Answer Key

Total Marks: 55
Topic: Whole Numbers (up to 10 million)

Section A (10 marks)

1. (2 marks)
Answer: Four million two hundred five thousand three hundred eighteen.
Teaching note: Read number in groups of three from left: 4 | 205 | 318. 4 million, 205 thousand, 318.
Common mistake: writing "four million two hundred five thousand three hundred and eighteen" (and not needed in SG format but acceptable). No "and" before thousand group standard.

2. (2 marks)
Answer: 7 000 000 (seven million).
Teaching note: Digit 7 is in the millions place (leftmost). Value = 7 × 1 000 000.

3. (2 marks)
Answer: 7 000 000.
Teaching note: 6 849 572 is between 6 million and 7 million; since 849 572 > 500 000, round up to 7 million.

4. (2 marks)
Answer: 9 060 412.
Teaching note: nine million = 9 000 000; sixty thousand = 060 000; four hundred twelve = 412. Combine: 9 060 412.

5. (2 marks)
Answer: Ten thousands.
Teaching note: 2 913 480 → digits: 2 (millions), 9 (hundred thousands), 1 (ten thousands), 3 (thousands)… So 3 is in ten thousands place.
