In this three-page packet, students practice present tense, stem-changing verbs in Spanish by making a study chart and then by playing a series of Tic-tac-toe (Te Ta Ti) games. There are two different study charts included for different levels of students. One is blank and the other has the stems lightly filled in for students to copy over and then add the correct endings. Vosotros is included, but can be left out of the study guide. Vosotros is not included in the Te Ta Ti game. In the Te Ta Ti game, pronouns have been randomly filled in and students must correctly conjugate the verbs in order to put their mark in the space. Game variations might include: 1. Speed play: See how many games a pair can play in a given amount of time. 2. Elimination play: Have winners of one game play against winners of another to determine a class champion. 3. Team play: Have students form groups of 4 or more, and compete as teams. All students on one team will fill out their game boards the same way, but will take turns saying the verbs. 4. Roundtable play: Students play each game against a different partner, regardless of winners and losers.
