Le labeur du Monstre-Facteur
The mathematical word featured in this episode is: side. The Monster-Postman is distraught. He has to deliver the mail, but the Lichette Monster has licked all the stamps on all the envelopes. And without a stamp on the envelopes, the Monster-Postman cannot distribute them. He must therefore put stamps on all the envelopes and he calls on the Maths Monster Squad to come to his aid. The monsters will have to sort the envelopes according to their shape and then place them in the correct monster-stamper.
