A meitats de mar\u00e7 les matem\u00e0tiques es fan notar: se senten, flueixen, es deixen veure a l\u2019Institut Vila-seca.<\/p>\n
Ja ha tornat a arribar el 14 de mar\u00e7 i un cop m\u00e9s hem celebrat el dia Pi, 3-14 (aix\u00ed els anglesos denominen el 14 de mar\u00e7), igual que l\u2019inici d\u2019aquest nombre tant matem\u00e0tic, tan m\u00e0gic, tan \u00fatil i tan… llarg*!<\/p>\n
Enguany hem estat nost\u00e0lgics (o pr\u00e0ctics) i hem repetit activitats d\u2019altres anys, \u00a0les m\u00e9s vistoses, les que m\u00e9s ens havien agradat fer:<\/p>\n
1r ESO: la cadena de colors llaaaarga de decimals del n\u00famero pi. Ens hem superat i hem arribat a les 2600 xifres decimals: \u00a0Enhorabona alumnes de primer!<\/p>\n
2n ESO: els calidocicles de cada any.<\/p>\n
3r ESO: els alumnes han intentat emular a Escher, l\u2019artista (matem\u00e0tic?) de construccions impossibles, exploracions de l\u2019infinit i tessel.les, reproduint el seu fam\u00f3s mosaic de sargantanes<\/p>\n
4t ESO: uns kirigamis i fractals molt acolorits.<\/p>\n
Com sempre, \u00a0gr\u00e0cies a tothom, alumnes i professors, per la vostra col\u00b7laboraci\u00f3 i bones intencions.<\/p>\n
Per\u00f2 aix\u00f2 no \u00e9s tot. Dijous 15 de mar\u00e7 ha continuat la setmana m\u00e9s matem\u00e0tica de l\u2019any: alumnes de 1r i 3r d\u2019ESO i de 1r i 2n de BAT han participat a la XXIII Prova Cangur, \u00a0que organitza la Societat catalana de matem\u00e0tiques de l\u2019Institut d\u2019Estudis Catalans.<\/p>\n
Gr\u00e0cies als alumnes de l\u2019Institut que heu estat pensant aquesta hora i quart en problemes de l\u00f2gica i raonament matem\u00e0tic. Un dels problemes de nivell de 1r BAT ha estat:<\/p>\n
\u201cLes longituds dels dos costats d\u2019un triangle s\u00f3n 5 i 2, i la longitud del tercer costat \u00e9s un nombre enter imparell. Quina \u00e9s la longitud del tercer costat?<\/p>\n
A) 7 \u00a0 B)6 \u00a0 C)5 \u00a0 D)4 \u00a0 E)3\u00a0 \u201c<\/p>\n
En saps la resposta?<\/p>\n
*Alguns diuen \u201cel nombre pi \u00e9s infinit\u201d, haurien de dir, \u201ct\u00e9 infinites xifres decimals\u201d, si fos infinit no podria estar entre el 3 i el 4, no?<\/p>\n
