Geometry is the best course for students to obtain systematic training on logical thinking in mathematics. Many students do not have a good chance to get proper training in logical reasoning at school. This course will teach students basic elements in Geometry, the properties and relationships among those elements. These elements include lines, triangles, quadrilaterals, polygons, circles and solid shapes. In addition to basic concepts in Geometry, logical reasoning will be emphasized during the progress. The course will also teach students how to prove a Geometric proposition in a formal way with reasons for each step. After this course, students will be well trained and prepared for high level math learning. Course Plan: This course needs a total of 22 lessons to cover the entire contents, starting from early January until mid-June. After completing this course, the student can continue to take Algebra-2 class in the following summer/fall session.
