Ever enjoy the classic math game called "Minute Math?" This "Un Minuto Loco" activity focusing on Spanish E to IE present tense stem-change verbs will capture the attention of ALL of your students. Set a timer for one minute and challenge students to conjugate as many of the verbs in the given subject as they can. This makes a great "Hazlo Ahora" or Exit Ticket and is a great piece of formative assessment.
If you teach from the Avancemos 1 textbook, this activity corresponds to the Unidad 4 Lección 1 unit.
