Here is an idea for a course in toki pona, which I found on another conlang (Kah) site.:

Have multiple short lessons; maximum 8 or 10 new words per lesson. No grammar explanations, just a simple story. Story line builds as student
gains more vocabulary. Story is not translated, just presented so the student can figure out the meaning from the vocabulary. The idea is that
the short little vocabulary for each lesson is the only thing that has to be translated, to make the course tailored for ANY language. So toki pona
would be accessible to be learned by anyone.

I have attempted to translate the first 3 lessons into toki pona using this approach.
Please let me know if I have made any mistakes, or could present the ideas in a better way, especially where the characters address each other and give commands.

Lesson 1
