• Course Description:

    This course is intended to formalize and extend students’ geometric experiences from the middle grades. Students explore more complex geometric situations and deepen their explanations of geometric relationships, moving towards formal mathematical arguments. Students apply transformations in this course to support a deeper understanding of the geometric concepts. This course is the study of the size, shape, and position of figures in space. It consists of the development of an understanding of mathematical proof, the improvement of the quality of thinking in non­mathematical situations, the introduction of the manner in which algebra and geometry complement each other, and the realization of plane and space relationships. Through the Mathematical Practice Standards students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations.
