One of the pdf files is not a pdf, but a TaskMagic3 Mix&Gap file (the one with 'change to mtx3' in the name - change the extension from pdf to mtx3 after downloading to be able to access with TaskMagic3). The other 2 files are a gap-fill and a text re-ordering activity based on the song 'Mon beau sapin' (sung to the tune of 'O Christmas Tree'). The web link is to a page which explains how to use MixéGap files in TaskMagic3.
