Algorithmique du cycle 3 - 6e

Déplacements

Exercice 1 : Déplacement véhicule - Découverte du bloc 'Tourner' (3/6)

Essayer à nouveau de positionner la voiture face à la tour.

Exercice 2 : Déplacement véhicule - Utiliser plusieurs blocs (2/6)

Utiliser maintenant le bloc autant de fois que nécessaire pour atteindre la tour.

Exercice 3 : Déplacement véhicule - Découvrir l'algorithmie par bloc (1/6)

Déplacer le bloc pour faire avancer le véhicule vers la tour.

Exemple:

Exercice 4 : Déplacement véhicule - Utiliser une boucle plus complexe (5/6)

En utilisant toutes les connaissances découvertes dans les exercices précédents,

Réaliser un algorithme permettant d'amener le véhicule face à la tour d'arrivée.

Exercice 5 : Déplacement véhicule - Trouver son chemin parmi plusieurs possibles (6/6)

Réaliser un algorithme permettant d'amener le véhicule à côté de la tour d'arrivée et positionné face à elle.

Attention : Vous ne pouvez utiliser que 8 blocs en tout !
