Help your students understand Spanish stem-changing verbs in the preterite with this Sudoku game. Students complete the puzzle by numbering the boxes 1 to 9. Each column and row adds up to 45, and no number is repeated in the same row or column. This allows for students to check their work. Along the bottom of the page, there is a guide for students to refer to in order to know how they should number the boxes. Each number in the guide corresponds to a verb and a subject pronoun. The students must find the conjugation of that verb according to the guide and number the boxes accordingly.
Stem-changing verbs with O-->U and E-->I changes are included.
