Bar charts and line graphs are both useful tools for showing information, but they each have their own special ways to do it.

Bar Charts:

• What They Are: Bar charts use bars that stand up tall or lay flat to show amounts for different groups. The longer the bar, the bigger the number it represents.
• When to Use Them: They are great for comparing different groups. For example, you could use a bar chart to show how many pets students have in different classrooms.
• How to Read Them: You can easily see how one group compares to another just by looking at the height or length of the bars.

Line Graphs:

• What They Are: Line graphs use points that are connected by lines to show how things change over time or in a sequence. Each point stands for a specific number linked to a particular time or event.
• When to Use Them: They are perfect for showing trends or changes, like how temperatures go up and down over a month.
• How to Read Them: The angle of the line tells you if the information is going up or down—steeper lines mean faster changes.

In short, use bar charts when you want to compare different groups and line graphs when you want to show changes over time. Each type of chart has its own strengths for showing data clearly!
