As any non-native Spanish-speaker will attest to, there is nothing more difficult than learning to conjugate those irregular Spanish verbs. Fortunately, the quizzes from Quiz Tree can help. Each quiz, with twenty-five to fifty questions apiece, targets specific basic Spanish infinitives, such as �estar� (to be), �jugar� (to play), and �hacer� (to make). The multiple-choice questions ask students to identify the proper conjugation of the selected verb in each tense (including the preterito impefecto) taking the subject into consideration (nosotros, etc.). These activities are excellent resources for instructors who teach beginning or intermediate Spanish courses to use in the classroom or as supporting material. They are also helpful for students new to Spanish or who need to refresh their rusty Spanish skills. Qu� bueno!
