CI MATEMTIQUES 1

Podem classificar les activitats de clcul segons lhemisferi cerebral que utilitzem per dur a terme el procs numric:

El clcul global t lloc a la part dreta del cervell. El clcul analtic es dna a la zona esquerra.En el clcul global es processa la informaci a partir dimatges. Per exemple, si proposem el problema se-

gent: 2 pomes i 3 pomes, quantes pomes sn?Els alumnes el resoldran a partir dimatges: veuran les pomes i desprs respondran. En aquest procs de

resoluci no hi ha una seqncia, la resposta es veu a linstant.En el clcul analtic es processa la informaci a partir de smbols numrics. Si preguntem: Quant fan 15 ms 30?Els alumnes ho resoldran amb processos de comptatge: sumaran primer les unitats i desprs les desenes;

o amb mtodes ms perfeccionats, com ara sumar primer 10 i 30 i, tot seguit, afegir-nhi 5. Aquests processos sn seqenciats; al contrari dels globals, desprs es poden explicar.

Els alumnes, per poder dur a terme el clcul analtic, han dhaver adquirit un gran nombre de destreses. s necessari que tinguin un gran domini del nostre sistema de numeraci, i amb aquesta finalitat cal fer activitats com les segents:

Comptar de manera ascendent i descendent dun en un, de dos en dos, de tres en tres, etc. Determinar els nombres anterior i posterior duna srie numrica. Buscar la desena ms prxima. Buscar un nombre situat entre uns altres dos. Determinar el nombre ms gran o el ms petit dentre dos nombres.

Nivells de clcul analtic del Quinzet

Els nivells estan organitzats de menys dificultat a ms.Tant la formulaci de les preguntes de les activitats com la resoluci daquestes es fa oralment. La resposta

es pot donar per escrit.s aconsellable fer dos nivells a la setmana.
