Good evening, @espooner ...
Do you use Canvas Commons at your school? If so, you can share an entire module to Canvas Commons, and then your colleague at your school can import that module from Commons to his/her own course.
I hope this will help a bit. Sing out if you have any questions about this...thanks! Take care, stay safe, and be well.
You can also copy the course to a sandbox, delete everything you don't want to pass to the other instructor and then export the course. When they import it, they will just get the module you gave them.
