Section A: Reading Picture Graphs (Questions 1 to 5)

Context for Q1-Q5: The picture graph shows fruits sold on Monday. Each symbol represents 2 fruits. This means to find the actual number, we multiply the number of symbols by 2.

Question 1

Answer: 10 apples Marks: 1 Explanation: The row for Apple has 5 symbols. Each symbol = 2 apples. So, 5 × 2 = 10 apples. Teaching Note: When a picture graph uses a scale (each symbol = more than 1), we must multiply the number of symbols by the scale to find the actual value. Here, 5 symbols × 2 apples per symbol = 10 apples. Common Mistake: Students might count only the symbols (5) instead of multiplying by the scale (2).

Question 2

Answer: 6 bananas Marks: 1 Explanation: The row for Banana has 3 symbols. 3 × 2 = 6 bananas. Teaching Note: Same method as Q1. Always check the scale of the picture graph first.

Question 3

Answer: Apple Marks: 1 Explanation: Apple has 5 symbols (10 apples), Banana has 3 symbols (6 bananas), Cherry has 4 symbols (8 cherries), Durian has 2 symbols (4 durians). Apple has the most symbols, so it has the most fruits sold. Teaching Note: We can compare either the number of symbols or the actual values. Since each symbol represents the same number (2), comparing symbols is faster.

Question 4

Answer: 4 more cherries Marks: 1 Explanation: Cherry has 4 symbols (8 cherries). Durian has 2 symbols (4 durians). Difference = 4 symbols - 2 symbols = 2 symbols. 2 × 2 = 4 more cherries. OR 8 - 4 = 4 more cherries. Teaching Note: "How many more" means we subtract the smaller from the larger. We can find the difference in symbols (4 - 2 = 2 symbols) and then multiply by the scale (2 × 2 = 4), or find the actual values first and subtract.

Question 5

Answer: 28 fruits Marks: 1 Explanation: Total symbols = 5 + 3 + 4 + 2 = 14 symbols. 14 × 2 = 28 fruits. OR 10 + 6 + 8 + 4 = 28 fruits. Teaching Note: "Altogether" means we add all the values. We can add the symbols first and then multiply by the scale, or find each actual value and add them.

Section B: Interpreting Picture Graphs (Questions 6 to 10)

Context for Q6-Q10: The picture graph shows books read by four children. Each symbol represents 2 books.

Question 6

Answer: 8 books Marks: 1 Explanation: Ali has 4 symbols. 4 × 2 = 8 books. Teaching Note: Same method as Section A. Always check the scale first.

Question 7

Answer: Bala Marks: 1 Explanation: Bala has 6 symbols, which is the most. 6 × 2 = 12 books. Teaching Note: Compare the number of symbols or the actual values. Bala has the longest row of symbols.

Question 8

Answer: 22 books Marks: 1 Explanation: Bala has 6 symbols (12 books). Devi has 5 symbols (10 books). 12 + 10 = 22 books. OR 6 + 5 = 11 symbols, 11 × 2 = 22 books. Teaching Note: "Altogether" means add. We can add the actual values or add the symbols and multiply by the scale.

Question 9

Answer: 6 more books Marks: 1 Explanation: Bala has 6 symbols (12 books). Cindy has 3 symbols (6 books). 12 - 6 = 6 more books. OR 6 - 3 = 3 symbols, 3 × 2 = 6 more books. Teaching Note: "How many more" means subtract the smaller from the larger.

Question 10

Answer: 36 books Marks: 1 Explanation: Total symbols = 4 + 6 + 3 + 5 = 18 symbols. 18 × 2 = 36 books. OR 8 + 12 + 6 + 10 = 36 books. Teaching Note: "In total" means add all the values. Check your addition carefully.

Section C: Drawing and Completing Picture Graphs (Questions 11 to 15)

Context for Q11-Q15: The table shows stickers collected by three friends. Each star symbol = 2 stickers.

Question 11

Answer: Students should draw a picture graph with:

• Emma: 4 star symbols
• Farid: 3 star symbols
• Gina: 5 star symbols Marks: 1 Explanation: Emma has 8 stickers, so 8 ÷ 2 = 4 stars. Farid has 6 stickers, so 6 ÷ 2 = 3 stars. Gina has 10 stickers, so 10 ÷ 2 = 5 stars. Teaching Note: To draw a picture graph from a table, we divide the actual number by the scale to find how many symbols to draw. The graph should have a title, labels, and the correct number of symbols. Marking Note: Award 1 mark for correct number of symbols for all three friends. Deduct if symbols are not neatly drawn or if the graph is not labelled.

Question 12

Answer: 4 star symbols Marks: 1 Explanation: Emma has 8 stickers. Each star = 2 stickers. 8 ÷ 2 = 4 stars. Teaching Note: This is the reverse of reading a picture graph. Instead of multiplying, we divide.

Question 13

Answer: 5 star symbols Marks: 1 Explanation: Gina has 10 stickers. 10 ÷ 2 = 5 stars. Teaching Note: Same method as Q12. Divide the actual number by the scale.

Question 14

Answer: Gina Marks: 1 Explanation: Gina has 10 stickers, which is the most. She needs 5 star symbols. Teaching Note: We can compare the actual numbers from the table or the number of symbols in the graph.

Question 15

Answer: 14 stickers Marks: 1 Explanation: Emma has 8 stickers. Farid has 6 stickers. 8 + 6 = 14 stickers. Teaching Note: "Altogether" means add. This question uses the actual numbers from the table, not the symbols.

Section D: More Practice with Picture Graphs (Questions 16 to 20)

Context for Q16-Q20: The picture graph shows ice creams sold. Each symbol represents 3 ice creams.

Question 16

Answer: 12 ice creams Marks: 1 Explanation: Monday has 4 symbols. 4 × 3 = 12 ice creams. Teaching Note: The scale is different here (each symbol = 3). Always check the scale before calculating.

Question 17

Answer: 6 ice creams Marks: 1 Explanation: Tuesday has 2 symbols. 2 × 3 = 6 ice creams. Teaching Note: Same method as Q16.

Question 18

Answer: Wednesday Marks: 1 Explanation: Wednesday has 5 symbols, which is the most. 5 × 3 = 15 ice creams. Teaching Note: Compare the number of symbols or the actual values. Wednesday has the longest row.

Question 19

Answer: 9 more ice creams Marks: 1 Explanation: Wednesday has 5 symbols (15 ice creams). Tuesday has 2 symbols (6 ice creams). 15 - 6 = 9 more ice creams. OR 5 - 2 = 3 symbols, 3 × 3 = 9 more ice creams. Teaching Note: "How many more" means subtract. We can work with symbols or actual values.

Question 20

Answer: 42 ice creams Marks: 1 Explanation: Total symbols = 4 + 2 + 5 + 3 = 14 symbols. 14 × 3 = 42 ice creams. OR 12 + 6 + 15 + 9 = 42 ice creams. Teaching Note: "Altogether" means add all the values. Double-check your addition.
