This booklet is the second booklet of my conjugation series. It builds upon my Livret sur le Présent de l'indicatif. In this booklet, students will find simplified explanations of when we use the imparfait and how to figure out the imparfait of verbs. The booklet starts out with the basics of être and avoir and proceeds to the regular verbs in -er, their small variations, 2nd group verbs in -ir, irregular -ir verbs and the rest of the 3rd group of verbs. After each exercice section, there is a quiz. I do not always give the quiz as an actual "quiz" but I use it as a self-evaluation tool for the students. In the back, there is also an answer key to the exercises.
