I think that this book is very good to use in a kindergarten or firs grade class in order to explain the purpose of bulldozers. The style of this book is very easy to read and understand. Each page has short sentences that describe the functions and parts of the bulldozer. Also, included in the book are very helpful and realistic pictures. On the pictures are arrows that point out the different parts of the bulldozer, which i found to be very helpful. At the end of the book was an index/word list that list the parts of the bulldozer and the corresponding page in the book. ( )
