If you just have 12 periods of 1 hour to teach, what would you teach? What is the most important content teachers should teach to secondary students?

I have 12 hours to teach to my adult students (no more). In january, I will finish this period and in february I will teach another 12 periods of time. So I need to improve it because what I taught I have a presentiment it is not to be *the most important* in mathematics: thinking and reasoning about facts (math or real). #classroom #teaching

#Adults #Mathematics #teacher. Looking for non-magisterial activities and their integration in class. Using almost always free (as in freedom) contents.
