This sample site for setting up a Level 2 Haiku Class. It provides several different ways to layout units or modules in a class. It uses discussions and assignments to engage students.
I use this reference page all the time. It shows you where the "embed" code is for a variety of different tools. In Haiku LMS, you'd copy the embed code from these examples into the Add Content Block>Embed the Web feature.
This is an excellent example of a Level 3 class. It has multiple subject areas, organized into gradebooks with student work submitted, assessed and handed back to the student.
