This book describes child labor in Kensington, Philadelphia during the early 20th century. It tells of Mother Jones's efforts to end child labor and of her organized march from Philadelphia to New York. Currie does an excellent job of including facts and quotes from sources, and he even admits that some of the facts contradict themselves. The book includes numerous black and white photos. Teachers can use these photos to have students infer what is going on in the picture. English teachers can have students look at newspaper articles about the march and then have students create their own newspaper article. Math teachers can use this book to look at what the average family made and how much money they really needed to survive. They can also have students compare that budget to families in today's society. History teachers can use this as a source to teach students about the Great Depression and about why we have child labor laws in place now. Currie uses a clear style of writing that is easy for the reader to understand. It follows a chronological order starting around the year of 1903. The black and white photos also enhance the book by allowing the reader to see what life actually looked like back then. It also includes a table of contents, a bibliography, and an index. This is an excellent source for a teacher or a librarian to use. ( )
