Strengths: Pete the Cat is always a big hit in the elementary school library. I mean, what's not to love. Pete is a very hip and funny cat. In this book, he's got a coat with four groovy buttons. Unfortunately, they're always popping off. But Pete doesn't cry. Goodness no, buttons come and buttons go. He just keeps on singing his groovy song. Easy subtraction from 4 to 0 included in the text.
Weaknesses: I would not dare to call Pete weak for fear of a retaliatory scratching!
