Rationale for using Topic 90 is to provide convenience and consistency in curriculum planning. Whereas Activities (on this site) almost always directly correspond to a topic … techniques do not. Techniques are almost always agnostic toward a specific subject area – therefor do not apply to a specific topic. Techniques are useful across all subject areas.

By codifying lessons as “Topic 90” – an instructor can quickly identify these “agnostic” lessons.
