Une technique chinoise de multiplication très originale

04/25/2007

Elle nous vient du péril jaune, il s'agit d'une technique très géométrique de multiplication.

Je me souviens qu'en Afrique francophone en général, savoir multiplier revient à connaître par coeur des tables de multiplication, et pas mal d'élèves ont dû en baver. Les tables de multiplication par 7, 8 t 9 étant souvent celles qui posent le plus de problèmes.

La méthode présentée ici ne requiert que de savoir compter, et de savoir un p'tit peu dessiner. Je me demande combien d'élèves calculeraient mieux s'ils connaissaient cette méthode.

Regardez, c'est tout en vidéo, sans besoin d'explication orale
