The fundamental purpose of Integrated Mathematics I is to formalize and extend students' understanding of linear functions and their applications. The critical topics of study deepen and extend understanding of linear relationships, in part by contrasting them with exponential phenomena, and in part by applying linear models to data that exhibit a linear trend. Mathematics I uses properties and theorems involving congruent figures to deepen and extend understanding of geometric knowledge from prior grades. The Integrated Mathematics courses follow the structure began in the K-8 standards of presenting mathematics as a coherent subject, mixing standards from various conceptual categories. This course includes the standards from the Common Core State Standards. Included are the conceptual categories of Number and Quantity, Algebra, Functions, Geometry, and Statistics and Probability.
