**Great Graphing Resources Grades 1-8**

Have you ever noticed how ocean waves move? The up and down pattern that they makes is called a **wave graph**. Such graphs are an important part of science topics such as sound, heat and energy. Believe it or not, the heart pumps blood in a wave pattern also which can be drawn on a graph.

Graphs are a part of everyday life. In fact, we use them daily for directions and counting! For example, if I'm explaining the directions to my home to a friend, I might say the Petrol Pump is on your left, take a left turn from there, I can also easily sketch these directions on a graph. If a newspaper story says that 30% of the world's teenagers say that chocolates are their favorite snack, this can be shown better with the help of a graph.

Graphs are a part of math in almost every grade. It's an important topic to learn as it has several advantages. The biggest advantage of learning how to use graphs is that it makes it easy to display information. Very complicated facts and figures can be easily explained when displayed on a graph. Graphs are like pictures that speak a thousand words!

Computer softwares like **Microsoft Excel** have made it very easy to make graphs you can also choose your graph's colors and type to make it more attractive! Engineers, researchers, scientists, doctors, astronomers, and pilots all make use of graphs regularly. So what are we waiting for? Let's start learning how to graph!

**Math Graph Basics**

Graphs are drawn on a **coordinate plane**. This is a flat space made by two lines which are **perpendicular** to each other, which means that the two lines make an angle of **90 degrees** with each other. The space they create is called a plane. On that plane, the horizontal axis is called the **X-axis** and the vertical axis is the **Y-axis**.

Using the x-axis and y-axis we can plot points on the coordinate plane. For example, a point with coordinates (4, 3) means that the point is 4 spaces to the right on the x- axis and 3 spaces upwards on the y- axis. Where do we move upwards and right from? This is from the point called the **origin** which has coordinates (0, 0).

This was just a basic description of graphs which will help you understand the coordinate plane. We can learn all the concepts of graphs online.

**Different Types of Graphs**

There are several types of graphs and each type is especially suited for different types of information. The following are some of the most commonly used graphs:

**Line Graphs:**A straight lines drawn on the coordinate plane refers to a line graph. There can be more than one line. These lines show how two**variables**(usually x and y) are related to each other i.e. how changes in one variable affect the other variable.

An easy example could be the line graph of your mum's shopping expense! The x-axis could show the items bought and the y-axis shows the total bill. A line graph in this case will explain how increasing items increases the shopping bill. The **slope** of a line graph is very important and shows how fast one variable is changing as compared to the other. A line graph is a way to summarize how two pieces of information are related and how they vary depending on one another. The numbers along the side of the line graph are called the scale.

**Pie Charts:**A pie chart is a circle graph divided into pieces where each piece of the pie displays the size of some related piece of information. Hence, pie charts are used to display the sizes of parts that make up the whole.

For example, you could have a pie chart of all the people in your school. One piece could be girl students, another piece could be boy students, and another could be teachers!

**Bar Graphs:**These are graphs which consist of an axis and a series of labeled horizontal or vertical bars that show different values for each bar. A graph with horizontal bars is called a horizontal bar graph and one with vertical bars is called a vertical bar graph. The numbers along a side of the bar graph are called the**scale**.

We could use a bar graph to display the number of different types of cars in the city. So the horizontal axis could have the car names on it like Toyota, Honda and Suzuki. The vertical bars will become the scale in this example showing the number of cars. Each vertical bar would have a different length which would represent the number of the type of car.

There are many other types of graphs including: **column graphs**, **box-plot**, **area graphs** and **polar graphs**. You can learn all about these at:
