Users of the guide are cautioned that some of the reviewed materials are dated, and the indicated costs may have gone up over time. We suggest contacting publishers or distributors of the materials for an updated cost before ordering. This section is added only when needed and may contain comments on the features of the materials or provide additional information, like whether or not the package provides teacher workshops or additional publications. In the rare case that an item or package reviewed is so obviously biased that teachers could be uncomfortable including it in a class lesson, we comment accordingly in this section. It includes lists of available materials, sometimes with annotations and descriptions.
Information is often spotty on both availability and distribution.
In this section we simple relate what an agency or publisher says regarding the materials' connections to standards and grade level appropriateness. If they state their correlation with standards is unknown, that is what is indicated. Format and organization. References National Council for the Social Studies. National Research Council.
