Tract plays nicely with any Learning Management System (LMS) you may be using. If you are using Tract for instructional time, you may want to assign work to your class.
The most common ways teachers can assign work includes:
Assigning a general goal to reach by a given date
Assigning a specific learning path to complete by a given date
Assigning a specific challenge to complete by a given date
Assigning a collection of learning paths to choose from and complete by a given date
See below for detailed instructions using Google Classroom (the flow is similar in Canvas, Seesaw, Schoology, or any other LMS).
Assigning a general goal
Assigning a goal gives students maximum choice, while still providing milestones they must reach by a given date. The most commonly used goals are:
Complete X challenges
Complete Y learning paths
Create a learning path
Earn Z coins
Here is an example assignment using Google Classroom:

You can directly link to the Tract's explore page if your assignment requires students to complete paths or challenges, or to Tract's create page if your assignment involves creating a learning path.
Set the grading/points to ungraded or pass/fail.
Set a due date.
Optionally, set a topic (ex. Coding, Science, World Culture) and include any additional rubric you will be using.
Assigning specific learning paths and challenges
Assigning a specific learning path or challenge allows you to easily integrate Tract into your instructional time and relate it closely with your curriculum. If you don't find something that exactly matches what you are looking for, Tract's community of hundreds of Creators can make it for you within days!
Start by searching our content library using filters, tags, and text search to locate the exact topic you want. As an example, I searched "water cycle" and found The cycle that never ends...The Water Cycle!.

After clicking on the learning path, you now have the option to copy the link to the learning path trailer/first mission, or a specific challenge.

Challenge Link Example (pictured below)

Now in your LMS, you can assign the specific learning path or challenge.

Set the grading/points to ungraded or pass/fail.
Set a due date.
Optionally, set a topic and include any additional rubric you will be using.
Often times teachers will curate a list of learning paths or challenges to choose from so students have more choice. In this case, you can use a Google Doc to curate a list of links or provide each learning path they can choose from as its own link in the LMS. Modify the instructions to explain the optionality.
