Les CM2 ont d\u00fb relever un d\u00e9fi assez compliqu\u00e9.<\/p>\n

La maitresse leur a demand\u00e9 de tracer \u00e0 la craie sur la cour, les figures planes qu’ils \u00e9tudient en ce moment.<\/p>\n

Ils n’avaient pas d’instruments de g\u00e9om\u00e9trie \u00e0 leur disposition. Il a fallu se d\u00e9brouiller et r\u00e9fl\u00e9chir en \u00e9quipe pour r\u00e9aliser des rectangles, triangles \u00e9quilat\u00e9raux, parall\u00e9logrammes et rosaces avec de la ficelle, une baguette et une feuille de papier \u00e0 plier en gabarit d’angle droit.<\/p>\n

Cela n’a pas \u00e9t\u00e9 facile, mais ils y sont parvenus gr\u00e2ce \u00e0 une bonne coop\u00e9ration. Le plus difficile a \u00e9t\u00e9 de faire les rosaces car les ficelles devaient \u00eatre bien tendues pendant le trac\u00e9 !<\/p>\n
