I didn't much like book one of this series, but book two is fabulous! Elementary age students are able to choose the best answers to complete sentences, make inferences, decide whether or not a sentence makes sense, and choose the answer that makes the most logical sense. They are able to practice numerous critical thinking skills.
I think it's great to encourage critical thinking or logic skills among young children. They're quite able to learn these skills!
This book would be terrific for homeschoolers, other educators, and parents who want to work with little ones on these skills at home.
