Bar Graph: A visual way to show information using bars of different heights.
Data: Information that is collected and shown in a graph.
Categories: Different groups or topics shown on the graph (like colors, animals, fruits).
Values: The numbers that tell how many or how much for each category.
Scale: The numbers on the side of the graph that show the value of each bar.
- Read the graph title: Understand what the graph is about
- Look at categories: See what each bar represents
- Check the scale: Look at numbers on the side to see what each unit means
- Read each bar: Find where the top of the bar meets the scale
- Answer questions: Use the information to solve problems
- Check your work: Make sure answers make sense
• Always read the title first to understand what the graph shows
• Count carefully from the bottom of each bar to its top
• Pay attention to question words to determine the operation needed
• Provide complete answers with proper units and context

Reading Bars: Start at bottom (0), go to top of bar, read the number.
Comparing: Taller bars = bigger numbers, shorter bars = smaller numbers.
Operations: "More than" = subtract, "Total" = add, "How many" = read the value.
Checking: Always verify your answer makes sense with the graph.
Answering: Include units (people, books, etc.) in your response.

Question 1: 9 apples
Question 2: 9 - 5 = 4 more apples than oranges
Question 3: Apples (tallest bar)
Question 4: 9 + 6 + 5 + 4 = 24 fruits altogether
