This outer space themed activity contains 28 fill-in-the-blank flashcards targeting irregular past tense verbs. The target verb is provided in the blank but must be conjugated by the student. A twenty-sentence screening activity is also included to evaluate whether students can discriminate between appropriate and inappropriate irregular past tense verb conjugation. Simply color in the smiley face for "correct use" or the sad face for "incorrect" use. This activity could be used for work on present and future tense verb conjugation as well. Enjoy!
