Aquest curs, com ja sabeu, ens hem convertit en uns grans experts en balenes blaves i, investigant sobre aquests animals, hem treballat moltes mates.<\/p>\n

Tot va comen\u00e7ar quan vam llegir a la classe el conte Hi ha res m\u00e9s gran que una balena blava<\/em>? Al conte explicava que la balena blava fa uns 30 metres de llargada aproximadament. Llavors ens va sorgir una pregunta: Hi cabria una balena blava a la classe? Vam pensar les opcions que ten\u00edem per mesurar-la i ens vam posar mans a l’obra. Amb la cinta m\u00e8trica vam mesurar la llargada, l’al\u00e7ada i l’amplada de la classe i vam poder comprovar que no ens hi cabia. Aix\u00ed que vam\u00a0decidir comprovar si cabria al pati. El vam mesurar de diferents maneres: amb el nostre cos, amb la cinta m\u00e8trica, amb els pl\u00e0nols i fins i tot amb un mesurador l\u00e0ser! Vam fer molts c\u00e0lculs, vam treballar amb n\u00fameros for\u00e7a grans i vam poder comprovar que ens hi cabia una balena blava al pati. A la pista ens hi cabia una i a la resta de pati, dues balenes adultes m\u00e9s i una cria.<\/p>\n

Al conte tamb\u00e9 s’explicava que les balenes blaves pesen 150 tones. Despr\u00e9s d’investigar qu\u00e8 eren les tones i quants quilos eren 150 tones, ens va sorgir una segona pregunta:\u00a0quants nens i nenes necessitem per pesar tant com una balena blava? Els submarins i submarinistes vam pensar que necessit\u00e0vem pesar a tots els nens i nenes de la nostra escola. Els exploradors marins, que necessitar\u00edem pesar a tots els nens i nenes de totes les escoles de Castellar: vam fer enquestes, vam escriure cartes… Per\u00f2 sobretot, vam fer una gran feina de c\u00e0lcul: vam aprendre a fer servir la calculadora, a fer aproximacions i a treballar amb n\u00fameros molt per\u00f2 molt grans!!! Amb tot, ni pesant a tots els nens i nenes de les escoles de Castellar vam tenir prou per pesar tant com una balena blava! 150.000 quilos s\u00f3n molts quilos!!!<\/p>\n

Per\u00f2 la nostra feina matem\u00e0tica no va acabar aqu\u00ed. Est\u00e0vem tan motivats amb les balenes blaves que vol\u00edem organitzar un viatge per anar a buscar-les. Era una mica dif\u00edcil aix\u00ed que vam pensar\u00a0a organitzar un viatge imaginari i per a organitzar-lo era imprescindible elaborar una guia de viatge. El lloc escollit van ser les illes A\u00e7ores, ja que era el lloc m\u00e9s a prop de casa nostra on pod\u00edem trobar balenes blaves. Vam haver de fer un pressupost de viatge: vam treballar amb euros i sumar moltes quantitats (preu dels bitllets, de l’allotjament…). Tamb\u00e9 vam haver de fer c\u00e0lculs per a saber quant de menjar i quanta beguda ens calia per passar una setmana fora de casa i tot, multiplicant-ho per 27!!!<\/p>\n

Si us animeu a anar a\u00a0buscar\u00a0balenes blaves o voleu saber m\u00e9s sobre aquests animals marins ja sabeu, nom\u00e9s heu de consultar\u00a0el nostre bloc!<\/p>\n
