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).

Does anyone know how to set up a face headset microphone + some bluetooth speaker? In classrooms with face mask some students will not hear me very well. @Gina perhaps know some. Thanks in advance, I also searched for transparent face mask for deaf people but I don't know the level of protection of such masks rather than aproved by Governements. How do you set up for next classes in the season 2020-2021?

Des de dilluns 16/3/2020 fins dilluns 30/3/2020 no hi haurà classe a les IB per mor de Coronavirus [twitter.com/EDUN_IB/status/123]. A l'espera de les instruccions de la Conselleria d'educació i com gestionar els contactes amb els alumnes. Com afectarà això als majors de 25 anys i les proves d'accés a la UIB?

Today I revise lcm, gcf, fraction operations, simplications (secondary equivalent level) with groups. At the end, students should have one word with 16 characters!. I attach images with some instructions (in catalan)

Who says examens must be individual? Who says probability must be theoretic? Students of 10th grade in adult education, answer in pairs probabilistic questions. See exam questions [and answers] (in catalan) and how they work.

Monday May 13th, students answered the question: what's the probability of one person chosen randomly hits the return of sound in Whitney Houston "I will always love you" and Roxette "She's got the look". Inspiration from El Hormiguero [antena3.com/programas/el-hormi]. You can see the results of times and percentage of interval. We have to count errors. We set error < 5% is hit and otherwise fail (but really it needs more precision)

What's the longest distance the water jet will reach? I plan to use it to explain parabolic trajectory (projectile motion). Does anyone know how to emulate this building a device? The idea is to increase the water flow and then calculate the reaching distance. How do you construct such a device?
