Bar Graphs and Pictographs — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A pictograph shows Bikes=7, Cars=4, Buses=2 symbols (key=10). How many more bikes than buses?
A) 30
B) 40
C) 50
D) 60
Bikes are 7 x 10 = 70 and Buses are 2 x 10 = 20. The difference is 70 - 20 = 50 more bikes.
2. A bar graph shows Store A=45, Store B=30, Store C=55, Store D=20. What do Store C and Store D total?
A) 65
B) 75
C) 85
D) 70
Read each bar and add: Store C's 55 plus Store D's 20 totals 55 + 20 = 75.
3. A pictograph shows Math=8 and English=5 symbols (key=5). How many more students like Math?
A) 3
B) 10
C) 15
D) 20
Math is 8 x 5 = 40 and English is 5 x 5 = 25. 40 - 25 = 15 more students prefer Math.
4. Three bars on a graph show 20, 30, and 40. What is the total of all three bars?
A) 80
B) 90
C) 100
D) 70
Sum the three bar heights together: 20 + 30 + 40 = 90 is the combined total.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A pictograph shows Tigers=6, Elephants=9, Monkeys=4 symbols (key=5). Total animals: 95.
Add the symbols first: 6 + 9 + 4 = 19. With a key of 5, multiply 19 x 5 = 95 animals.
2. A bar graph shows Class A=35 and Class B=25. Class A collected 10 more cans.
The difference between the two bars is 35 - 25 = 10, so Class A collected 10 more cans.
3. To show 45 on a pictograph with a key of 5, you need 9 symbols.
Divide the value by the key to find how many symbols you need: 45 divided by 5 is 9 symbols.
4. Bar graph values Mon=15, Tue=20, Wed=25, Thu=30, Fri=10. The week total is 100.
Add every bar across the week: 15 + 20 + 25 + 30 + 10 = 100 for the full total.
5. A pictograph shows 5 full symbols and one half symbol with a key of 4. The value is 22.
Five full symbols are 5 x 4 = 20, and half a symbol is half of 4, which is 2. Adding gives 20 + 2 = 22.
