Bar Graphs and Pictographs — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A pictograph shows Eagles = 6, Hawks = 9, Owls = 5, Falcons = 4 symbols (key = 10). What is the grand total?
A) 220
B) 240
C) 200
D) 260
Add the symbols across every row: 6 plus 9 plus 5 plus 4 = 24 symbols, then multiply by the key value of 10 to get a grand total of 240 birds.
2. A bar graph shows Jan = 15, Feb = 25, Mar = 40, Apr = 20. How much more rain fell in March than in January?
A) 15
B) 20
C) 25
D) 30
Subtract January's bar from March's bar to find the rainfall difference: 40 minus 15 leaves 25 more units of rain in March.
3. A pictograph uses a key of 8. A row shows 3 full symbols and a half symbol. What is the value?
A) 24
B) 32
C) 28
D) 20
Three full symbols stand for 3 times 8 = 24, and a half symbol means half of 8 = 4, so 24 plus 4 gives 28.
4. A bar graph shows Team X = 50, Team Y = 35, Team Z = 45. Which pair totals exactly 85?
A) X and Y
B) Y and Z
C) X and Z
D) All three
Try each pair: X plus Y is 50 plus 35 = 85, while X plus Z gives 95 and Y plus Z gives 80 — only X and Y land on 85.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A pictograph shows Drums = 5, Guitar = 8, Piano = 3 symbols (key = 10). The total instruments are 160.
Add the symbols across rows: 5 plus 8 plus 3 = 16 symbols, then multiply by the key value of 10 to get 160 instruments in all.
2. A bar graph shows Store 1 = 60, Store 2 = 40, Store 3 = 50. The average per store is 50.
To find the average, add all three bars (60 plus 40 plus 50 = 150) and divide by the 3 stores: 150 divided by 3 equals 50 per store.
3. To show 56 on a pictograph where each symbol equals 8, you need 7 symbols.
Divide the total by the key value to find how many symbols to draw: 56 divided by 8 equals 7 symbols.
4. A bar graph shows Library A = 70 and Library B = 45. Library A lent 25 more books.
Subtract Library B's bar from Library A's bar to compare them: 70 minus 45 leaves 25 more books lent by Library A.
5. A pictograph shows 7 full symbols and one half symbol with a key of 6. The total is 45.
Seven full symbols stand for 7 times 6 = 42, and a half symbol means half of 6 = 3, so 42 plus 3 gives 45.
