Can you help with an interesting title for teaching materials?

I am preparing, organizing, and putting together some teaching materials for a college course that is split into two courses. I’m looking for some help and ideas on how to organize the materials into two texts/guides, one for each course respectively: Course I and Course II. (Courses are ESP related.)

How should I refer to such materials compilation? Text?
Guide?

I’d like ideas on:
• Title for the text/guide
• The main division of the contents is: Unit 1, Unit 2, Unit 3. I need a name for the sub-divisions of each unit (I also have 3 sub-divisions for each unit). Like this:
Unit 1
X1
X2
X3
• Each subdivision has materials for one full lesson and contains: theory, exercises and readings. What name can I give to the theory section?
• If I include two or more readings. What name is better: Reading 1, Reading 2 or Text 1 or Text 2, or…?
• At the end of the book I am planning to include extra info such as special vocabulary, glossaries, graphic organizers, Exams Format model. How should I label this section?

All ideas/comments are greatly appreciated.
