Some course materials useful for teachers
Overleaf offers a course by its founder, John Lees-Miller, in three parts:
Overleaf also has a webinar-format intro of LaTeX for biologists: http://bitesizebio.com/webinar/20591/latex-for-biologists/ and three-part introductory series of blog posts (from Arin Basu in New Zealand):
Speaking of Overleaf, here is an example of a project done on this platform in Russian): July Tikhonov taught a 8-hours class for eight-graders using a combination of LaTeX and Asymptote. As he writes,
The plan was to introduce them to an example project with minimal configuration, and explain basics like where are comments and what is preamble and where is the document.
After that, I got them to copy the project and type some problems (taken from their olympiadic math courses, actually) with solutions; since the group was small, I could mentor each of them on using relevant LaTeX constructs, Russian language constructs and style, and Asymptote.
Here are example projects I used (all in Russian):
