This is a game to practice conjugating stem changing verbs in the preterite tense. In order to earn the X or O on the game board, students have to correctly conjugate the verb. You can have the students play in groups of three - two students play and the third student is the judge. Rotate roles for each game. An answer key for the judge is included.
This pair drill is included in my stem changing verbs bundle. Find it at the link below.
