# Insert Math Equations into Lesson Plan

This is a feature available to Chalk Gold subscribers and teachers whose schools are subscribed to our paid solutions.

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.

This support article goes over how to use the math editor in the context of your lesson planning. If your school is subscribed to our Curriculum option, you can also use the editor within your curriculum maps.

## Insert Math Equations

Open a lesson you want to insert math equations for and click the

**Insert Math**icon on the formatting menu.When you open the math editor, it defaults to the

**Graphical Editor**option. Here you can use your keyboard inputs to enter simple codes and functions and review a visual demonstration of how they will appear when you insert them into your lessons.Click the Toggle Virtual Keyboard icon (keyboard) next to the input field to toggle a virtual keyboard that you can use to input various commands.

Click the

**Use LaTeX Editor**button to switch to a LaTeX command input format.You can also use the LaTeX editor for chemical equations by using the

**\ce**command. For example, \ce{H2O}.

When you are done entering the content, click

**Insert**,

Once you have 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.

## LaTeX Commands

LaTeX is a command system for technical or mathematical typesetting that is used by mathematicians worldwide. Use the LaTeX option in the math editor to embed complex mathematical formulas directly into your lesson plans.

The math editor feature supports over 800 LaTeX commands.
