"Listen and Read" Stories

These 54 free stories will be the perfect start to develop vocabulary while building interest in learning and reading.  Older children will find something that interests them because the collection is divided into eight categories: social studies, science, plants and flowers, environmental stories, civics and government, animals, American history, and community.
