The MathThematics program is a complete mathematics curriculum that promotes student success and engages students in learning by using a thematic approach, active learning, and varied practice and assessment. The mathematics content for each level is presented in one book containing eight thematic modules that connect the mathematical ideas to real-world applications. Each modules contains four to six sections, an Extended Exploration, a Module Project, and a Review and Assessment. McDougal Littell MathThematics is based on the field-test versions of the STEM (Success Through Exploring Mathematics) Project curriculum. The STEM Project was supported in part by the National Science Foundation (NSF).
