# How do I insert math equations into my lesson plans?

**This is a feature available to Chalk Gold subscribers and teachers whose schools are subscribed to our paid Chalk solutions. You will not have this option if you are a free user.**

Including math equations in your lessons can be valuable for comprehension and delivery for STEM-based subjects, but can be difficult to include through plain text. This article will show you how to insert math equations and formulas directly into your lessons through our lesson editor.

**Note: **This support article goes over how to use the math editor in the context of your lesson planning, but if your school is subscribed to our Curriculum option then you will be able to use the editor within your curriculum maps as well.

## Step 1:

Open a lesson you would like to insert math equations for and click the math editor icon in the formatting menu, as shown below.

## Step 2:

When you first open the math editor, it will default to the **Graphical Editor **option. Here you can use your keyboard inputs to enter simple codes and functions and see a visual demonstration of how they will appear when you insert them into your lessons.

Click the icon to the right of the input field to toggle a virtual keyboard that you can use to input various commands.

You can click the **Use LaTeX Editor **button to switch to a LaTeX command input format. For more information on using LaTeX commands in the math editor, please read the "What LaTeX commands are available?" section at the bottom of this support article.

**Note: **You can also use the editor for chemical equations by using the \ce LaTeX command, such as "\ce{H2O}" shown below.

## Step 3:

When you've completed entering the content, click **Insert **and it will be embedded into your lesson as an image.

## Step 4:

Once you've inserted a math equation into your lesson, you can click on it to display a menu of available editing options. You can resize the image, change display options, add captions, or edit the equation contents as necessary.
