Aquesta setmana, els alumnes de 4t hem assolit un dels grans reptes del curs en l’\u00e0rea de matem\u00e0tiques: les divisions de dues xifres<\/b>. Per\u00f2 no ens hem quedat nom\u00e9s amb el llapis i el paper; hem traslladat aquest nou coneixement al laboratori de rob\u00f2tica per programar una calculadora de divisions amb la nostra placa Micro:bit<\/b>.<\/p>\n

Entendre l’algorisme per poder-lo programar<\/h4>\n

Programar una calculadora no \u00e9s nom\u00e9s pr\u00e9mer tecles. Perqu\u00e8 la Micro:bit ens doni el resultat correcte, els alumnes han hagut d’entendre primer l’estructura l\u00f2gica de la divisi\u00f3. A trav\u00e9s del pensament computacional, hem hagut de definir clarament els conceptes que estem treballant a classe:<\/p>\n

    \n
  • \n

    El Dividend:<\/b> El n\u00famero que volem repartir (assignat al Bot\u00f3 A a les desenes i B a les unitats).<\/p>\n<\/li>\n

  • \n

    El Divisor:<\/b> Entre quants el repartim (assignat al Bot\u00f3 A+B a les desenes i el logotiop a les unitats).<\/p>\n<\/li>\n

  • \n

    El Quocient:<\/b> El resultat que la placa ens mostra en agitar-la (el shake<\/i>). O els m\u00e9s agoserats ho hem fet amb el sensor de volum. Qu\u00e8 millor que un bon crit per saber-ne el resultat?<\/p>\n<\/li>\n<\/ul>\n

    El valor del residu: M\u00e9s enll\u00e0 del resultat exacte<\/h4>\n

    Un dels punts clau de la propera sessi\u00f3 ser\u00e0<\/strong> com gestionar el residu<\/b>. A difer\u00e8ncia de les calculadores convencionals que sovint donen decimals, nosaltres hem programat la Micro:bit perqu\u00e8 ens digui el quocient sencer i quant sobra.<\/p>\n

    Aquesta part \u00e9s fonamental dins del programa PCMAT<\/b>, ja que obliga l’alumne a reflexionar sobre qu\u00e8 passa quan una divisi\u00f3 no \u00e9s exacta, refor\u00e7ant el concepte matem\u00e0tic mentre busquen el bloc de codi adequat.<\/p>\n

    Matem\u00e0tiques i programaci\u00f3: Un t\u00e0ndem d’\u00e8xit<\/h4>\n

    L’activitat ha servit per perdre la por a les “dues xifres”. En veure que s\u00f3n capa\u00e7os de crear una eina que resol aquests c\u00e0lculs, els alumnes guanyen confian\u00e7a en les seves habilitats matem\u00e0tiques.<\/p>\n

    Hem apr\u00e8s que si som capa\u00e7os d’explicar-li a un robot com es divideix, \u00e9s perqu\u00e8 realment nosaltres ja ho hem ent\u00e8s!<\/p>\n
