Save The Tree House (Pre-level A1/level 4)

There's a park in the town, with beautiful trees. Yet, someone wants to cut them all down and build a shopping centre. But there's a tree house in one of the trees, and five children who are not going to leave the park, or their tree house. Can the five children save the trees and their tree house ? Il y a un parc en ville, agrémenté de très beaux arbres. Cependant, il est question de les raser pour construire un centre commercial.
Mais cinq enfants s'y opposent fermement. Parviendront-ils à sauver le parc et leur cabane dans l'arbre ?
