What Are Line Graphs? Let's take a look at what they are one by one, and then we can move on to learn how you can read them! A graph is a visual illustration of data that is too big and too complicated to be written in text. And a line graph is a type of graph. And trust us, they are super helpful! There is so much that you can learn from looking at one of them. A line graph usually looks like a graph looks like a connect-the-dots puzzle; these dots and the line connects the dot to make a representative of the information. Line graphs can be straight, curved, or dotted! Reading line graphs is very easy. There are two axes, the x, and the y-axis, that have the numbers and values. These values represent the data of the question, and the line represents the highs and lows. The higher the line, the greater the value, and the lower the line, the lower the value.

We use line graphs to get a picture of a value over time. For example if you wanted to track the amount of money you had in the bank, you would have twelve bars over the course of a year to display this. If we are trying to compare two data sets, a line graph could have two lines. This is really helpful to do when we are trying to find relationships between two different sets of data. These worksheets explain how to read and plot line graphs. Sample problems are solved and practice problems are provided. Your students will use these activity sheets to learn how to create line plots to track data points that change over time. Students will also learn how to construct line plots.
