Bar Graphs and Pictographs — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A pictograph shows Swimming=9, Soccer=6, Dance=4, Art=7 symbols. Key: each symbol = 5. What is the total?
A) 120
B) 130
C) 140
D) 110
Bikes = 7 × 10 = 70, Cars = 6 × 10 = 60. Total: 70 + 60 = 130 vehicles.
2. A bar graph shows Mon=20, Tue=35, Wed=15, Thu=30, Fri=25. How many more books were sold on Tuesday than Wednesday?
A) 15
B) 20
C) 25
D) 10
Subtract Thursday from Tuesday: 45 − 25 = 20 more.
3. A pictograph uses a key of 4. Dogs shows 3 full symbols and one half symbol. How many dogs are there?
A) 12
B) 16
C) 14
D) 10
4 full symbols = 4 × 3 = 12, 2 half symbols = 2 × 1 = 2. Total: 12 + 2 = 14.
4. A bar graph shows Red=30, Blue=20, Green=25. What is the combined total for Red and Green?
A) 50
B) 55
C) 45
D) 60
Add both values: 30 + 25 = 55.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A pictograph shows Apples=8, Bananas=5, Cherries=6 symbols (key=10). The total fruit sold is 190.
Add all days: 50 + 45 + 35 + 25 + 35 = 190.
2. A bar graph shows Feb=25 and Mar=30. Together they equal 55.
The combined total of Red and Blue: 30 + 25 = 55.
3. To show 35 on a pictograph where each symbol equals 5, you draw 7 symbols.
Multiply the number of symbols by the key value: 7 × 1 = 7.
4. On a bar graph, the tallest bar shows 40 and the shortest shows 10. The difference is 30.
Subtract the smaller from the larger: 45 − 15 = 30.
5. A pictograph shows 4 full symbols and one half symbol with a key of 2. The total is 9.
3 full symbols = 3 × 2 = 6, 3 half symbols = 3 × 1 = 3. Total: 6 + 3 = 9.
