Grammar can be a difficult area to target while maintaining a high level of student engagement. These interactive books were designed to provide students with a hands on approach to learning irregular past tense verbs! Irregular past tense verbs can be a difficult concept for many children to grasp, but these interactive books can be used over and over to provide repeated practice to struggling students. The interactive books target the present progressive verb tense in addition to the irregular past tense. The irregular past tense verbs included in these two interactive books were chosen with care to ensure that the words students are practicing are functional words that they encounter daily.
