I have a Mathematics degree and Master (Word Problem in Groups) from University of Balearic Island (UIB). Now I'm secondary teacher teaching adults. I'm looking for non-magisterial activities and their integration in class. My aim now is to *build* thinkers in my classroom. Dan Meyer [] has impact on me

Les eines que he emprat en aquest confinament han estat 1) Google Classroom per administrar notes i passar tests als alumnes, 2) Jitsi per fer videoconferències setmanals per a cada curs i 3) Khan Academy per fer tests automàtics.

El proper curs vull substituir el Google Classroom per una eina lliure, possiblement Numbas, INGInious, R/examen o Moodle. Encara que el meu centre vol emprar massivament Google Classroom i la Conselleria d'Educació *obliga* a emprar GClassroom o Teams de Microsoft(!)

Finalment, el COVID-19 ha fet que el professorat (ni l'alumnat) del meu centre no anàs a classe des de dia 13 de març fins dia 22 de juny. Dia 22 de juny el professorat s'ha d'incorporar per fer reunions fins dia 30 de juny. L'alumnat ja no s'incorporarà fins el curs que ve.

El proper curs, que començarà el setembre, la Conselleria d'Educació contempla tres escenaris: presencialitat, semipresencialitat i classes a distància depenent de la situació del coronavirus.

I found Numbas and it's what I need. I'm secondary teacher of maths and this is perfect for COVID-19 homework administration without using non-free software. Thanks a lot @christianp for your effort. @3rik Erik please take note for wiki recommendations against COVID crisis in website.

Des de dilluns 16/3/2020 fins dilluns 30/3/2020 no hi haurà classe a les IB per mor de Coronavirus []. 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?

Dia 25 de febrer vaig fer les meves al·legacions a l'esbós 2 de la futura llei de l'educació de les Illes Balears.

Primera passa de les Jornades de docents d'adults "Enxarxant els centres d’adults des de la cooperació": enviada la carta a tot el professorat del centres d'adults de les Illes Balears per "captar" a talleristes que vulguin compartir les seves experiències d'aula, de centre o de grup de docents. Adjunt document. Confirmada la ponència de Diego Redondo []

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)

I will participate in Make Math Moments Summit [] on November 16th and 17th. I hope it will be useful.

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 []. 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) My school and most schools in my regions migrate from moodle to Google Suite for Education because it's easy and it could control devices.

I warn about privacy issues, but never heard.

Is there any viable alternative to Google Suite for Education?. Control android devices is key for these schools.

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?

Next thursday I will do an activity with Vertical Non-Permanent Surfaces to solve quadratic equations. I plan to swap windows for correcting equations with another team and put +10 in my additive assessment sheet

This week I said to my students "how many digits do you use to approximate non-exact square root?" Almost everyone said 2. Why? They did not know. My opinion it's because math teachers repeadely told them
*without any reason*...

On Friday Feb 2nd, students do Dan Meyer's Graduation activity []. Their reasoning is to count time to pronounce names of 2, 3, 4 and 5 words and to count time between two graduates. Problems encountered: 1) missing people, 2) speakers omit words in names of 3+ words, 3) we have no time for seeing how much time speaker uses to pronounce names of 4 and 5 words [we use affine extrapolation for approximate it]. Final result: 12% of error of approximation #3-act
