Al m\u00f3n anglosax\u00f3 s\u2019acostuma a escriure primer el n\u00famero del mes seguit del n\u00famero del dia. Aix\u00ed el 14 de mar\u00e7 s\u2019escriu 3,14, \u00e9s a dir… una aproximaci\u00f3 de \u03c0. D\u2019aqu\u00ed que, internacionalment, el 14 de mar\u00e7 de cada any es consideri el Dia de Pi. <\/strong>A partir del 2020 la UNESCO el va declarar Dia internacional de les Matem\u00e0tiques.<\/p>\n

Com portem fent els \u00faltims anys, el nostre centre celebra aquest dia amb diferents activitats. Enguany alumnat de 1r de Batxillerat ha pintat un mural a un dels passadissos centrat amb el nombre Pi i amb les seves propietats. Els m\u00e9s petits del centre han buscat aproximacions d’aquest nombre mesurant per\u00edmetres i di\u00e0metres d’objectes circulars i alguns dels alumnes m\u00e9s grans ho han fet amb l’ajuda de programari com el GeoGebra i fent servir els M\u00e8todes de Monte Carlo. Alguns grups tamb\u00e9 han fet Pi-relats: microcontes on s’amaga el nombre Pi (cada paraula, ordenadament, ha de tenir la quantitat de lletres dels d\u00edgits de Pi).<\/p>\n

Durant aquesta setmana\u00a0tamb\u00e9 s’ha celebrat\u00a0 una de les grans “festes” de les matem\u00e0tiques: la Prova Cangur. El passat dijous 18 de mar\u00e7 175 alumnes del nostre centre (des de 1r d’ESO fins a 2n de Batxillerat) van participar en aquest concurs. <\/span>Les proves Cangur van comen\u00e7<\/span>ar a realitzar-se als anys 80 a Austr\u00e0lia. Actualment m\u00e9s de 60 pa\u00efsos organitzen la Prova Cangur dins d’un programa que es coneix com <\/span>Kangourou sans Fronti\u00e8res<\/em>. Al nostre pa\u00eds se celebra des de l’any 1999 i el Dertosa hi ha\u00a0<\/span>participat a totes les edicions. M\u00e9s enll\u00e0 dels resultats que puguin obtenir els alumnes, ens encanta la idea que l’alumant passi una bona estona raonant i resolent els 30 reptes matem\u00e0tics de la prova.<\/p>\n\r\n\t
