You can copy assignments/modules from one Canvas course to use in another Canvas course.
How to Copy a Module
Begin by navigating to the Canvas course that you want to copy content from.
Go to the modules section of your Canvas course.
You can choose to copy an entire module or an individual assignment/page/quiz.
To copy a module, locate it in your modules and select the 3 dots to the right of the module.
When you click the three dots, a drop-down menu will appear. Select the Copy To option.
Once you have clicked copy to, a sidebar will appear.
Enter the name of the course that you want to send the module to and then click Copy.
You will receive a message letting you know that the copy has successfully begun.
When the module has completed copying to the course, it will appear in the modules area as the very last module.
How to Copy a Single Assignment, Page, or Quiz
To copy a single assignment/page/quiz follow the same steps as you would to copy a module to another course.
You will select the individual item that you want to copy. When you click the three dots, a drop-down menu will appear. Select the Copy To option.
Once you have clicked copy to, a sidebar will appear. Enter the name of the course that you want to send the item to and then click Copy. Select which module you'd like to have it in, as well as, where in the module you'd like for it to go.
You will receive a message letting you know that the copy has successfully begun.
When copying is complete, your item will appear in the module that you sent it to.
