I would not really build an entire lesson around the activities in this book, but use them in the context of a unit which requires focus on parts of speech. The worksheets are engaging and fun, not the usual droll and uninspiring worksheets taken straight out of textbooks. I would use them as sponge activities, or as filler activities when there's some time left over at the end of a lesson. In doing so, instructional time can be utilized to its maximum and students will benefit from learning. This is an invaluable resource for LA teachers, grades 5 and up.
