This quick worksheet is a great way to check your students' understanding of the irregular preterite in Spanish; specifically, the verbs hacer, tener, estar, poder, ir, and ser.
A large space at the top has been provided for students to fill in the verb charts. If this is a new concept for them, you can have them copy the forms off the board, or if you feel that they should know these verbs in the preterite already, they can fill out the charts from memory.
Below that is a 13-sentence conjugation practice in which students must choose the infinitive that makes the most sense, then put it in the correct form.
Makes a great partial sub plan, or just use it during the last 15 minutes of class one day as a comprehension check or "ticket out the door"!
