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 [blog.mrmeyer.com/] has impact on me

Perhaps this is interesting [Sam Shah's Virtual Conference of Maths] twitter.com/samjshah2/status/1 (via GlobalMathDepartment).

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)

@switchingsocial@mastodon.at 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*...

Weeks #1 & #2 in ESPA 4 (secondary 10th equivalent in adults education in Balearic Islands): students solve Water Tank by Dan Meyer mrmeyer.com/threeacts/watertan . More information canterano.somenxavier.xyz/acti (in catalan)

Weeks #1 & #2 in ESPA 3 (secondary 9th level equivalent in adults education in Balearic Islands) [4-months courses]: 1) introduction [canterano.somenxavier.xyz/impl] (in catalan), 2) students resolved Coca-Cola Pool by Dan Meyer [101qs.com/3896] in groups and redacted reasoning brief. We use additive assessment with weights assigned by students [canterano.somenxavier.xyz/impl] [canterano.somenxavier.xyz/impl]. More information canterano.somenxavier.xyz/acti (in catalan)

On Friday Feb 2nd, students do Dan Meyer's Graduation activity [101qs.com/3530]. 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
