To learn about regular and irregular verbs, students can play this Turtle Diary game. Forming the past tense for regular and irregular verbs is different. The past tense of a regular verb that ends in a vowel is created by adding a "d." To create the past tense of regular verb that ends in a consonant, add "ed." The past tense of an irregular verb does not follow a pattern. Different forms of irregular verbs must be memorized. This lesson shares some commonly used irregular verbs and provides a basis for other Turtle Diary games that help student have fun and master language arts skills.
