Often called the "panhandle state" for its unique shape, Oklahoma is a rich land, full of hundreds of lakes and miles of rivers, thick, green forests, rolling mountains, and productive farmland. A True Book: My United States series allows readers to experience what makes each of the fifty state distinctive and exceptional. Readers will get to know each states' history, geography, wildlife and future outlook. This series includes an age appropriate (grades 3-5) introduction to curriculum-relevant subjects and a robust resource section that encourages independent study. Readers will get an up-close look at life in Oklahoma, from where people live to what their local traditions are. They will also learn about the state's history, government, economy, and more.
