Section A (10 marks)

Q1. Four million two hundred fifty thousand three hundred eighteen.
Teaching: Read each period: millions (4), thousands (250), ones (318).
Mark: 1

Q2. $7\,000\,000$ (seven million).
Teaching: Digit 7 is in the millions place. Value = $7 \times 1\,000\,000$.
Mark: 1

Q3. 9 604 020
Teaching: nine million = 9 000 000; six hundred four thousand = 604 000; twenty = 20.
Mark: 1

Q4. 4 000 000
Teaching: 3 847 291 → the million digit is 3, next digit 8 ≥ 5, so round up to 4 million.
Mark: 1

Q5. 5 312 004
Teaching: Compare digit by digit from left; at hundred-thousands: 3 vs 2, so first is greater.
Mark: 1

Q6. Hundred thousands
Teaching: 8 204 617 → digits: 8(mil), 2(hundred-thousands), 0(ten-thousands)…
Mark: 1

Q7. 6 500 000
Teaching: 6 549 999 → hundred-thousands digit 5, next 4 < 5, keep 6 500 000.
Mark: 1

Q8. Two million thirty thousand four hundred
Teaching: 2 030 400 → millions 2, thousands 030, ones 400.
Mark: 1

Q9. 1 000 002
Teaching: Smallest 7-digit using 1,2, and five 0s, no leading zero → 1 then zeros then 2.
Mark: 1

Q10. 9 999 000
Teaching: 9 999 499 → thousands digit 9, next 4 < 5, round down to 9 999 000.
Mark: 1

Section B (10 marks)

Q11. 3 045 210, 3 405 210, 3 450 210, 3 540 120
Teaching: Compare hundred-thousands: 0 < 4 < 4 < 5; then ten-thousands where equal.
Mark: 2 (both order and correctness)

Q12. Jan ≈ 2 300 000; Feb ≈ 3 200 000; estimated total = 5 500 000
Working: 2 345 678 → 2 300 000; 3 210 455 → 3 200 000; sum = 5 500 000.
Mark: 2 (1 for each rounding, 1 for total — allocate 1+1)

Q13. 5 730 000
Working: 5 734 892 → ten-thousands digit 3, next 4 < 5 → 5 730 000.
Mark: 2 (1 round, 1 state)

Q14. $6\,000\,000 + 7\,000 + 30$
Teaching: 6 007 030 = 6 millions, 0 hundred-thousands… 7 thousands, 0 hundreds, 3 tens.
Mark: 2 (expanded correctly)

Q15. 4 849 999

(c) 2 300 000 − 2 300 000 = 0 [1]
Working: B=2 354 890 greatest; A > C. Round A & C: both 2 300 000.

Q19.
(a) 4 500 000 [2]
(b) 5 499 999 [2]
