In this unit you will see that students are often asked to discern a pattern within a particular situation. This leads students to making conjectures and possibly generalizations that are both conceptual and procedural. you for looking at this unit and we welcome feedback and comments. Sincerely, Dr. Jonathan Katz (For the ISA math coaches) Unit 2 of Polygons: Triangles – Essential Questions: What makes a triangle unique? Interim Assessments/Performance Tasks Triangle Dilemma - Lesson 4 Possible Triangle Lengths - Lesson 5 Triangular Inheritance Lesson 12 – Final Assessment: Logo Design What will students understand and be able to do at the end of the unit? Students will develop a working definition of a polygon Students will develop an understanding of the big idea of with relationships” “reasoning as of understanding the similarities and differences between different triangles. Students will develop a complete understanding of triangles including proving theorems such as the measure of the interior angles of a triangle sum to 180 degrees, the inequality theorem, relationship of exterior angles to the two non-adjacent angles, joining midpoints of two of a triangle is parallel to the third side and half the length. Students will develop an understanding of concurrence through investigations and constructions with angle bisectors, medians and altitudes.
