I use this to introduce the P.C. with ETRE in level 2. On the first page, there is space to introduce the standard "Dr. & Mrs. Vandertrampp" acronym, but there is also a song on this side to help memorize the verbs as well.
On the second page, you start by choosing one verb as a class and conjugating it together. Then there are several practice sentences for students.
