In this for-credit course, students engage in lessons that focus on developing the critical thinking skills and habits of mind to solve advanced math problems. Taught through the use of exploration, pattern recognition, and technology, students will develop ideas and experiences that lead to formal geometric proofs and postulates. Creative problem-solving and ingenuity are critical skills for the course. Students will receive instruction and feedback on their development of these skills. Investigations include an introduction to the language of Geometry, recognition of invariants, congruence, areas and volumes, similarity, and circles. Students are required to meet expectations in understanding and mastering concepts, and developing independent applications. Students use the TI graphing calculator in the course. Non-Flint Hill students who complete this course receive Letter of Completion and not a Flint Hill Transcript.(1 Year Credit)
