A les classes de 2n d\u2019ESO B i E, un cop a la setmana, les matem\u00e0tiques es treballen d\u2019una manera diferent. L\u2019alumnat participa en sessions de resoluci\u00f3 de problemes on el repte, el raonament i el treball cooperatiu s\u00f3n els protagonistes.<\/p>\n\n\n\n

La din\u00e0mica \u00e9s senzilla per\u00f2 engrescadora: un \u00fanic problema, equips de tres alumnes formats a l\u2019atzar i una pissarra vertical per intentar resoldre\u2019l al llarg d\u2019una hora. Aquesta metodologia permet que els i les alumnes expliquin les seves idees, contrastin estrat\u00e8gies i construeixin el coneixement de manera compartida.<\/p>\n\n\n\n

Els objectius d\u2019aquestes sessions s\u00f3n desenvolupar les compet\u00e8ncies matem\u00e0tiques \u2014especialment la resoluci\u00f3 de problemes, el raonament i la comunicaci\u00f3\u2014, fomentar el treball en equip, afavorir una visi\u00f3 m\u00e9s positiva de les matem\u00e0tiques i augmentar el temps de pensament real de l\u2019alumnat durant la classe.<\/p>\n\n\n\n

Aqu\u00ed podeu veure un exemple:<\/p>\n\n\n\n

El repte de les 100 portes<\/strong>
En un passad\u00eds ben llarg hi ha 100 portes tancades i 100 claus numerades de l\u20191 al 100. Les claus tenen un encant m\u00e0gic: la clau n\u00famero n<\/em> obre totes les portes que s\u00f3n m\u00faltiples de n<\/em> (i nom\u00e9s aquelles). Inicialment, totes les portes estan tancades.
Un vigilant comen\u00e7a amb la clau 1 i obre totes les portes. Despr\u00e9s, amb la clau 2, canvia l\u2019estat de totes les portes m\u00faltiples de 2; amb la clau 3 fa el mateix, i aix\u00ed successivament fins a la clau 100.
\ud83d\udc49 Quines portes queden obertes al final? I quines tancades?<\/strong><\/p>\n\n\n\n

Aquesta manera de treballar les matem\u00e0tiques convida l\u2019alumnat a pensar, equivocar-se, dialogar i aprendre, convertint la classe en un espai actiu i participatiu.<\/p>\n\n\n\n
