This book is going to fill a need that many teachers have had for a long time. As you probably know, it has been just about impossible to find quality materials to help in sheltered or limited English US History classes. It was written by an experienced teacher with who has faced some of the same difficulties that you have. It is difficult to make history relevant and interesting to students with limited English and little experience with common American cultural and governmental traditions. The activities in this book are a blend of the course content in US History, and the grammar component that is necessary both for comprehension of the subject matter and general English fluency. The lessons in this book have two key components that will make your job a lot easier:

Hands-on sheltered classroom activities that take advantage of multiple learning styles and differing language acquisition levels. These are often very active and engaging.
Grammar exercises based on the vocabulary of the lesson that reinforce both grammar skills and the content area goals. These exercises will help build stronger readers and writers while reinforcing the main ideas of the course content in US History.
