Bar Graphs and Pictographs — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Soccer has 6 students because there are 6 symbols.
Corrected: Soccer has 30 students because each symbol equals 5.
The corrected sentence is: "Soccer has 30 students because each symbol equals 5.". The original sentence "Soccer has 6 students because there are 6 symbols." contained an error that needed to be fixed.
2. Fix the sentence:
Dogs and Fish together equal 35 pets.
Corrected: Dogs and Fish together equal 40 pets.
The corrected sentence is: "Dogs and Fish together equal 40 pets.". The original sentence "Dogs and Fish together equal 35 pets." contained an error that needed to be fixed.
3. Fix the sentence:
A half symbol on a pictograph means nothing.
Corrected: A half symbol on a pictograph means half the key value.
The corrected sentence is: "A half symbol on a pictograph means half the key value.". The original sentence "A half symbol on a pictograph means nothing." contained an error that needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. If each flower symbol equals 2, then 6 tulip symbols represent 12 tulips.
Multiply the number of symbols by the key value: 6 × 2 = 12 flowers.
2. A bar reaching 25 is 15 more than a bar reaching 10.
Subtract the smaller value from the larger: 25 − 10 = 15 more.
3. If each symbol equals 10 votes, then 5 pizza symbols show 50 votes.
Multiply the number of symbols by the key value: 5 × 10 = 50 votes.
4. The scale on a bar graph helps you read the exact value each bar shows.
The scale provides numbered intervals along the axis so you can determine the exact value each bar represents.
Part C: True or False?
Read each statement. Circle True or False.
1. If each symbol equals 5 and one row has 7 symbols while another has 3, the difference is 20.
True False
Bar graphs display data using rectangular bars whose lengths correspond to the values they represent.
2. A bar graph uses pictures instead of bars to show data.
True False
A key is essential in a pictograph because it tells you how much each symbol represents.
3. In a pictograph with a key of 2, four symbols equal 6.
True False
The same data can be shown with different symbols or key values, so two different pictographs can represent the same information.
