**Commentaires :
Les trois premières parties sont réalisables en 4ème .
La dernière partie n’est réalisable qu’en 3ème, en préambule ou en application des équations produits et du calcul littéral.
La construction et le problème peuvent être donnés en 6ème ou 5ème si l’objectif est de prendre en main un logiciel de géométrie dynamique et de conjecturer. Les parties C et D sont alors à ôter.
**Niveaux possibles :
Classes de quatrième / troisième.
**Logiciels utilisables :
Logiciel de géométrie dynamique.

First of all I want to say fantastic blog ! I had a quick question in which I’d like to ask if you don’t mind. I was interested to find out how you center yourself and clear your head before writing. I have had a difficult time clearing my thoughts in getting my ideas out. I truly do take pleasure in writing but it just seems like the first 10 to 15 minutes are generally lost simply just trying to figure out how to begin. Any ideas or tips ? Appreciate it !
