Regular verbs are the easiest to teach and should be the introduction to the future simple. Start by making four columns, with the labels “I.-are," “II. -ere," “IIIa. -ire" and “IIIb. -ire." Point out that both -ire verbs in the future simple have the same endings, just like in passato remoto and imperfetto; also, note that regular -are and -ere verbs also have the same endings. However, writing out all four will help reinforce it. Remind students that to conjugate the verb, the infinite ending (-are, -ere and -ire) are removed, then the future simple endings are added.
Once the endings have been explained on the blackboard, have students practice conjugating verbs in the future simple. First, make flashcards for each of the endings; do not include the person in front of it:
Pass out a flashcard to each student; make sure everyone has one, so repeat an ending if needed. On the blackboard, write one regular verb from each group (examples: cantare, credere, sentire and finire). Ask each student to read their flashcard out loud, identify what person the verb is, and whether it is an -are, -ere or -ire ending. Then, ask the student to choose the appropriate verbs from the blackboard and conjugate it to match her flashcard. If you need to make duplicate flashcards, add another verb on the board so each student does a different conjugation.
