There are 3 separate formative worksheets or quizzes here that review the irregular preterite tense including tener, hacer, decir, venir, ser, ver, ir, etc and the -car,-gar, -zar irregulars in the yo form. I have separated them and include a simple "verb chart" for each one that students can utilize as they practice the difficult irregulars in the preterite. The themes recycle vocabulary from Entreculturas 2 Units 1-5. The worksheets/quizzes can easily be adapted to any program.
