A very good elementary resource and usable at any level for ELL students, Teresa Domnauer’s Westward Expansion is intended for upper elementary audiences.  Covering the entire movement across the United States, from Beyond the Appalachians to Pathway to the Pacific, this 48 page history lesson is brief yet succinct.  The highlight is its bright color graphics throughout.  Additionally, important vocabulary is in bold and referenced in the glossary, following a resources page.  Another plus for this book is the critical thinking question given for each chapter that encourages the reader to read for “the truth” about the particular topic. Recommended for elementary libraries, additional purchase for secondary libraries.
