For social studies teachers, good social studies requires good reading, writing, and mathematics skills. In addition, the Pennsylvania System of School Assessment (PSSA) administers reading, writing, and mathematics assessments to students at specific grade levels. Through many years of working together with their classes and with the "We the People..." program, the co-developers of these instructional materials discovered the need to create interdisciplinary materials in reading, writing, and mathematics for social studies. These materials focus on the United States Constitution. The materials are divided into these sections: "Literature and Writing Connections"; "Literature and Writing: Elementary School"; "Literature and Writing: Middle School"; "Reading: Elementary"; "Math Strategies"; "Mathematics: Elementary School"; and "Mathematics: Middle School." The literature and writing connections section outlines literature links to Pennsylvania civics standards, while the literature and writing sections provide teaching strategies for teachers using quality literary selections with their students. The elementary reading section offers practical materials for reading improvement and textual understanding. The mathematics sections provide narrative mathematics problems for teachers to use with students to improve their mathematics skills. (BT)
