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:
The bar graph shows Bananas sold = 20.
Corrected: The bar graph shows Bananas sold = 15.
The corrected sentence is: "The bar graph shows Bananas sold = 15.". The original sentence "The bar graph shows Bananas sold = 20." contained an error that needed to be fixed.
2. Fix the sentence:
The pictograph uses a key where each symbol equals 1 pet.
Corrected: The pictograph uses a key where each symbol equals 2 pets.
The corrected sentence is: "The pictograph uses a key where each symbol equals 2 pets.". The original sentence "The pictograph uses a key where each symbol equals 1 pet." contained an error that needed to be fixed.
3. Fix the sentence:
Red received 10 more votes than Yellow.
Corrected: Red received 5 more votes than Yellow.
The corrected sentence is: "Red received 5 more votes than Yellow.". The original sentence "Red received 10 more votes than Yellow." 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 star symbol stands for 2 points, then 5 stars means 10 points.
Multiply the number of symbols by the key value: 5 × 2 = 10 points.
2. The day with the tallest bar on the graph sold the most books.
The tallest bar represents the greatest value, so that day sold the most books.
3. A pictograph key says each smiley face equals 5 students. Three smiley faces means 15 students.
Multiply the number of symbols by the key value: 3 × 5 = 15 students.
4. On a bar graph where each grid line equals 5, a bar reaching the third line shows 15.
Each grid line equals 5, so the 3rd line represents 3 × 5 = 15.
Part C: True or False?
Read each statement. Circle True or False.
1. In a pictograph where each symbol equals 2, four symbols represent 8 items.
True False
Pictographs use pictures or symbols to represent data values, with a key explaining what each symbol stands for.
2. A bar that reaches 20 is shorter than a bar that reaches 15.
True False
A shorter bar means a lower value. Taller bars represent higher values on a bar graph.
3. The key on a pictograph tells you how much each symbol is worth.
True False
The key (or legend) explains the value each symbol represents, which is essential for reading the graph correctly.
