In order to create a GeoGebra Lesson containing rich student tasks, you first need to create or find a GeoGebra Activity containing elements that transform into student tasks.

A GeoGebra Activity is an interactive (online) activity that combines different elements (e.g. text, applets, questions, videos, images) in a flexible layout. The online Activity Editor allows you to easily create a GeoGebra Activity yourself.  Learn how to create a GeoGebra Activity in our Learn how to use Resources tutorial.

A GeoGebra Activity can contain several elements. It is important to know which elements in GeoGebra Classroom will be tasks. The following elements become tasks in GeoGebra Classroom:

• Open questions
• Multiple-Choice questions
• GeoGebra apps (e.g.: GeoGebra Calculator Suite, GeoGebra Graphing Calculator, GeoGebra Classic)
• GeoGebra Notes applets

If a GeoGebra Activity contains at least one GeoGebra app or a question, a GeoGebra Lesson can be created directly from this Activity. Every app and every question from this Activity automatically becomes a task in the GeoGebra Lesson. Note: You can decide if your students will be able to view the correct answers on multiple-choice and open questions when creating a Lesson.

More than 1 million existing GeoGebra Activities and Books can now be used to start an interactive and live classroom discussion! You can search for already existing resources using our Math Topic Maps or the search bar on the GeoGebra website.
