To make a "regular" verb into a past tense verb, you simply add "ed" to the word (walk/walked, fix/fixed, etc.). Many verbs, however, are "irregular" in the past tense like, "run/ran," "catch/caught," etc. This Irregular Verbs Fun Deck is ideal for teaching these more difficult verbs. The deck has 26 pairs of present and future tense/irregular past tense verbs, extra bonus cards, and game ideas. Cards measure 2 ½" x 3 ½" and are stored in a sturdy storage tin.
