must (müssen), to be able to / can (können), want to (wollen), etc. are modal verbs (Modalverben). Like in English they are frequently used in written and spoken language. This powerpoint provides examples of the modals, discusses mögen as well as its subjunctive möchten and provides you with the conjugation tables of all modal verbs while providing important insight that shall help you teach or learn Modal Verbs! I further uploaded an exercise sheet to practice modals. Viel Spaß!
