This worksheet introduces students to irregular verbs through the adventures of time-traveling friends. Students will first rewrite verbs into their irregular past tense forms. Moving to Part 2, students fill in the blanks in ten sentences using verbs in their irregular past tense forms, guided by a helpful word bank. In Part 3, they'll write a sentence using any past tense verb related to time travel to Ancient Greece.

Transitioning irregular verbs to the past tense can be puzzling for fourth graders because these verbs don't follow the regular pattern of simply adding -ed. For instance, the verb "feed" becomes "fed" instead of "feeded," "do" changes to "did" rather than "doed," and "have" transforms into "had" instead of "haved."
