Travail préalable : calcul littéral (escaliers, suite de Fibonacci) et présentation des fractales.
Chaque élève doit être capable de présenter son résultat...
On voit apparaître des compétence de 4ème !!!
Un site intéressant : http://www.miqel.com/ il faut trier mais des idées sympas...
Travaux réalisés en ATP... utilisez compas... et décrire votre démarche... pas évident !
Activité en classe ( sur TBI )
