    Welcome to Ms. Thelusma's Geometry Class

    Ms. Thelusma has joined the math team at Peekskill High School and teaches 5 sections of Geometry. This year I look forward to working with the students at ensuring their success. Ms. Thelusma can be reached at mthelusma@peekskillschools.org

    Course Description

    The fundamental purpose of the course in Geometry is 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. Important differences exist between this Geometry course and the historical approach taken in Geometry classes. For example, transformations are emphasized early in this course. Close attention should be paid to the introductory content for the Geometry conceptual category found in the high school CCSS. The Mathematical Practice Standards apply throughout each course and, together with the content standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations.
