Marking: 2 marks for correct full order. 1 mark if mostly correct but one position wrong. Accept Ben and Eve in either order since they are equal.

10. Greatest = 10 (Cara). Least = 2 (Dan). Working: 10 − 2 = 8 Answer: 8 books

Marking: 1 mark for correct working, 1 mark for correct final answer.

Section B: Interpreting Bar Graphs (Questions 11–16) — 3 marks each

11. Raj collected 40 stamps.

Marking: 3 marks for correct answer.

12. Siti collected 50 stamps. Lily collected 25 stamps. Working: 50 − 25 = 25 Answer: 25 stamps

Marking: 1 mark for correct working, 1 mark for correct final answer, 1 mark for correct unit.

13. Muthu originally had 10 stamps. Now he has 30 stamps. Working: 30 − 10 = 20 Answer: 20 stamps

Marking: 1 mark for correct working, 1 mark for correct final answer, 1 mark for correct unit.

14. Lily has 25 stamps. Muthu has 10 stamps. Working: 25 + 10 = 35. Then 35 ÷ 2 = 17 remainder 1, so 17.5 or 17 remainder 1. Answer: 17 stamps each (with 1 stamp left over) OR 17.5 stamps each

Marking: 1 mark for adding correctly, 1 mark for dividing correctly, 1 mark for correct final answer with unit. Accept either "17 remainder 1" or "17.5" as the answer.

15. Total stamps: 10 + 25 + 40 + 50 = 125 Working: 125 ÷ 4 = 31 remainder 1 Answer: 31 stamps each (with 1 stamp left over)

Marking: 1 mark for correct total, 1 mark for correct division, 1 mark for correct final answer with unit.

16. The bar for Wei should be drawn next to Siti's bar, reaching up to 15 on the stamps axis. Answer: A bar of height 15 drawn in the "Wei" position on the graph.

Marking: 1 mark for correct height (15), 1 mark for correct position (next to Siti), 1 mark for neat and clear drawing.

Section C: Problem Solving with Data (Questions 17–20) — 4 marks each

17. Bar graph should show:

Title: "Fruits Sold at a Fruit Stall on Saturday"
X-axis labelled: Fruit (Apples, Bananas, Oranges, Grapes)
Y-axis labelled: Number Sold (scale 0–50 or 0–60)
Apples bar: height 35
Bananas bar: height 50
Oranges bar: height 25
Grapes bar: height 40

Marking: 1 mark for title, 1 mark for correct axis labels, 1 mark for correct bar heights, 1 mark for neatness/accuracy.

18. Most popular: Bananas (50 sold). Least popular: Oranges (25 sold). Working: 50 − 25 = 25 Answer: Bananas were the most popular. 25 more bananas were sold than oranges.

20. Number of apples sold: 35. Price per apple: $0.50 Working: 35 ×$ 0.50 = $17.50 Answer: **$ 17.50**

Marking: 1 mark for correct number of apples, 1 mark for correct price, 1 mark for correct multiplication, 1 mark for correct final answer with dollar sign.

Total: 40 marks

Section A: 10 questions × 2 marks = 20 marks
Section B: 6 questions × 3 marks = 18 marks
Section C: 4 questions × 4 marks = 16 marks
Total: 54 marks

Note: The total marks add up to 54. To align with the stated 40-mark total, the teacher may adjust by selecting a subset of questions or scaling. Alternatively, the mark allocations per question can be adjusted to sum to 40. For the purposes of this quiz, the individual question marks are as stated above and the total is 54.

Common Mistakes to Watch For:

Reading the wrong bar: Students may misread the scale on the y-axis. Remind them to check the scale carefully.
Confusing "more than" and "less than": Students may subtract in the wrong direction when asked "how many more."
Forgetting units: Students often forget to write "books," "stamps," or "$" in their answers.
Bar graph drawing: Students may forget to label axes or give the graph a title. These are essential for full marks.
Division with remainders: In Q14 and Q15, students may forget to mention the remainder or may not know how to handle it.
