Your teacher asks you to collect your classmates' opinions about their favorite school lunches. After asking everyone, you have collected a lot of data(数据) or information and aren't sure how to organize it. Creating a graph (图表) can be a great way to organize and share your data.

Graphs show data in a direct way that is easy to read and understand. There are many different kinds of graphs. Different graphs are better for different kinds of data. Read on to find out about the types of graphs in math, as well as the key parts of a graph.

Bar chart

A bar chart has a horizontal axis (横轴) and a vertical axis(竖轴). It has a title that explains what it shows, and different bars are used to show different amounts. There's a number line along the vertical axis and labels(标签) along the horizontal axis, labeling the data.

Pie chart

A pie chart helps organize and show data as a percentage of a whole. True to the name, it looks a bit like a pie and uses a circle to show the whole. Pieces of that circle, or "pie", stand for the different things. The different pieces of the pie are different sizes depending on how much of the whole pie they show. Each piece is labeled to show what it means.

Line graph

Line graphs are used to show changes to numbers over time. They show what we call continuous data. The vertical axis explains the data being shown. We mark data on a line graph. The different data points are then joined up with straight lines, so we can look at the trend(趋势) it shows.

Flow chart

A flow chart shows the different steps in something using boxes and arrows(箭头). It can often have many different directions and different paths you can take using the information it asks for. Flow charts can be great for explaining a huge process by breaking it down into different steps.

Food is interesting. It's also interesting that different food has different meanings in different countries. 

Onions ﹣﹣ In Egypt，many farmers use the onion as a symbol of truth （真理）. When they have different ideas with each other，they often have an onion in their hands and put it up high to show the truth is in their hands. A town in Switzerland has the Onion Festival. It is on the fourth Monday of November. Food shops and restaurants make all kinds of onion food on that day. 

Tomatoes ﹣﹣ They are the "Number 1" food. They are a kind of vegetable and a kind of fruit. They are very helpful. They're important to hamburgers and salad. They may taste bad if there are no tomatoes. In some countries of Europe，young men and women often pick tomatoes for each other when they are in love. 

Carrots ﹣﹣ We can usually see them in vegetable salad. In Netherlands （荷兰），the carrot，onion and potato are country food. People in some countries call the carrot "Queen". 

Potatoes ﹣﹣ They have two other names ﹣﹣ "apples in the forest" and "the second bread".
