Primary 3 Mathematics Quiz - Data Analysis (Answer Key)
Total Marks: 40
Section A: Multiple Choice Questions (10 marks)
1. Answer: (3) Cindy [1]
Working: From the bar graph, Cindy's bar reaches 16 books, which is the highest among Ali (12), Bala (8), Cindy (16), and Devi (4).
Teaching Note: To find who read the most, compare the heights of all bars. The tallest bar represents the greatest value.
2. Answer: (2) 20 [1]
Working: Peter has 4 stars (🌟🌟🌟🌟). Each star represents 5 stickers.
4 × 5 = 20 stickers.
Teaching Note: In picture graphs, always check the key to know what each symbol represents. Multiply the number of symbols by the value per symbol.
3. Answer: (4) Mango [1]
Working: From the table: Apple = 15, Banana = 12, Orange = 18, Mango = 9. The smallest number is 9 (Mango).
Teaching Note: "Fewest" means the smallest number. Compare all values in the table to find the minimum.
4. Answer: (4) Friday [1]
Working: From the bar graph, Friday's bar reaches 30 cars, which is the highest among all days (Mon=10, Tue=15, Wed=20, Thu=25, Fri=30).
Teaching Note: The tallest bar in a bar graph shows the maximum value. Read the value at the top of the bar against the vertical axis scale.
5. Answer: (2) 8 [1]
Working: Class 3C has 2 cookie symbols (🍪🍪). Each cookie represents 4 cookies.
2 × 4 = 8 cookies.
Teaching Note: Count the symbols carefully, then multiply by the value per symbol from the key.
6. Answer: (3) 40 [2]
Working: Wednesday = 80 visitors, Monday = 40 visitors.
Difference = 80 − 40 = 40 visitors.
Teaching Note: "How many more" means subtraction. Read both values from the graph accurately using the scale (intervals of 10), then subtract the smaller from the larger.
7. Answer: (3) 27 [2]
Working: Ahmad = 6, Bala = 9, Cindy = 12.
Total = 6 + 9 + 12 = 27 storybooks.
Teaching Note: Add the values for the specific pupils named in the question. Check you have selected the correct rows from the table.
8. Answer: (2) 18 [2]
Working: Sam has 2 circles (🔵🔵), Uma has 1 circle (🔵). Each circle = 6 marbles.
Sam: 2 × 6 = 12 marbles
Uma: 1 × 6 = 6 marbles
Total = 12 + 6 = 18 marbles.
Teaching Note: Calculate each person's total first, then add them together. Alternatively, add the number of symbols first (2 + 1 = 3), then multiply by 6 (3 × 6 = 18).
9. Answer: (2) 30 kg [2]
Working: Pumpkin B = 10 kg, Pumpkin D = 20 kg.
Total mass = 10 + 20 = 30 kg.
Teaching Note: Read the mass values from the vertical axis. The scale goes up in 5s, so check each bar's height carefully.
10. Answer: (2) 14 [2]
Working: Cindy = 52 stamps, Bala = 38 stamps.
Difference = 52 − 38 = 14 stamps.
Teaching Note: "Difference between" means subtract the smaller number from the larger number. 52 − 38 = 14.
Section B: Short Answer Questions (20 marks)
11. Answer: 45 pencils [2]
Working: Tuesday = 25 pencils, Thursday = 20 pencils.
Total = 25 + 20 = 45 pencils.
Marking: 1 mark for reading correct values (25 and 20), 1 mark for correct addition and answer with unit.
Teaching Note: Read each bar's value against the vertical axis. The scale is in intervals of 5. Tuesday's bar is halfway between 20 and 30 (25), Thursday's bar is at 20.
12. Answer: 9 cupcakes [2]
Working: Mike has 4 cupcakes (🧁🧁🧁🧁), Nina has 1 cupcake (🧁). Each cupcake = 3 cupcakes.
Mike: 4 × 3 = 12 cupcakes
Nina: 1 × 3 = 3 cupcakes
Difference = 12 − 3 = 9 cupcakes.
Marking: 1 mark for correct individual totals (12 and 3) or correct symbol count difference (3), 1 mark for correct final answer with unit.
Teaching Note: "How many more" requires subtraction. Find each person's actual total first using the key, then subtract.
13. Answer: 56 toys [2]
Working: Box A = 24 toys, Box C = 32 toys.
Total = 24 + 32 = 56 toys.
Marking: 1 mark for correct values from table, 1 mark for correct addition and answer with unit.
Teaching Note: Select the correct rows from the table (Box A and Box C), then add the numbers.
14. Answer: 40 cm [2]
Working: Plant T = 50 cm, Plant P = 10 cm.
Difference = 50 − 10 = 40 cm.
Marking: 1 mark for reading correct heights (50 and 10), 1 mark for correct subtraction and answer with unit.
Teaching Note: The vertical axis scale is in intervals of 10. Plant T reaches 50, Plant P reaches 10. Subtract to find the difference.
15. Answer: 24 badges [2]
Working: Amy has 4 badges (🏅🏅🏅🏅), Carol has 2 badges (🏅🏅). Each badge = 4 badges.
Amy: 4 × 4 = 16 badges
Carol: 2 × 4 = 8 badges
Total = 16 + 8 = 24 badges.
Marking: 1 mark for correct individual totals or combined symbol count (6), 1 mark for correct final answer with unit.
Teaching Note: "Altogether" means addition. Calculate each person's total using the key, then add.
Section C: Structured Questions (10 marks)
16. Answer: 14 pages [2]
Working: Peter = 52 pages, Mary = 38 pages.
Difference = 52 − 38 = 14 pages.
Marking: 1 mark for correct values from table, 1 mark for correct subtraction and answer with unit.
Teaching Note: "How many more" means subtraction. Peter read more than Mary, so subtract Mary's pages from Peter's.
17. Answer: 110 ice creams [2]
Working: Saturday = 60 ice creams, Sunday = 50 ice creams.
Total = 60 + 50 = 110 ice creams.
Marking: 1 mark for reading correct values (60 and 50), 1 mark for correct addition and answer with unit.
Teaching Note: The graph has 7 bars (Mon-Sun). Read Saturday and Sunday bars carefully. Scale is in intervals of 10.
18. Answer: 20 toy cars [2]
Working: Eric has 3 cars (🚗🚗🚗), Gary has 1 car (🚗). Each car = 5 toy cars.
Eric: 3 × 5 = 15 toy cars
Gary: 1 × 5 = 5 toy cars
Total = 15 + 5 = 20 toy cars.
Marking: 1 mark for correct individual totals or combined symbol count (4), 1 mark for correct final answer with unit.
Teaching Note: Multiply each person's symbols by 5, then add. Or add symbols first (3 + 1 = 4), then multiply by 5.
19. Answer: 16 kg [2]
Working: Watermelon W = 4 kg, X = 7 kg, Y = 5 kg.
Total = 4 + 7 + 5 = 16 kg.
Marking: 1 mark for correct values from table, 1 mark for correct addition and answer with unit.
Teaching Note: Add the masses of the three specified watermelons (W, X, Y). Do not include Z.
20. Answer: 20 pupils [2]
Working: Class 3D = 35 pupils, Class 3E = 15 pupils.
Difference = 35 − 15 = 20 pupils.
Marking: 1 mark for reading correct values (35 and 15), 1 mark for correct subtraction and answer with unit.
Teaching Note: Read the bar heights for 3D and 3E. Scale is in intervals of 5. 3D is at 35, 3E is at 15. Subtract to find how many more.
