Jeu: pizza deluxe Tous les morceaux de pizza sont éparpillés, face contre table. Chacun son tour, on peut: Faire tourner la roulette et on trouver la fraction parmi les morceaux éparpillés. Le joueur peut garder le morceau si c’est la bonne fraction. OU Faire une transaction équitable (échanger 1 demi pour 2 quarts) Le premier joueur qui complète une pizza gagne. NB: Si un joueur a trop de pizza, il peut en débuter une seconde mais on ne peut plus les mélanger.

Le terme du bas s’appelle le DÉNOMINATEUR: il indique combien de parties il faut pour faire le tout. Exemple: 2 ← numérateur 3 ← dénominateur
