Westside High School Backwards-Design Lesson Plan Template 2014-2015 Geometry Prep Unit 3 Writing Equations of Lines Unit 9/29 – 10/3 Stage 1 – Desired Results Student Outcomes (objectives): Understanding (s)/goals: Essential Question(s): EU1: Apply slopes and equations of lines to investigate geometric relationships, including parallel lines, perpendicular lines, and special segments of triangles and other polygons. EQ1: Equations of lines pervade mathematics studies and their applications to the real world. 1. What effects do the characteristics of lines have on their equations? 2. Given a point and a line, what variety of lines can be written/created? EQ2: 1. What are the benefits of point-slope form? EU2: Students work with point-slope form to write equations of lines where slopeintercept is not as adaptable. GEOM.7A Use one- and two-dimensional coordinate systems to represent points, lines, rays, line segments, and figures. GEOM.7B Apply slopes and equations of lines to investigate geometric relationships, including parallel lines, perpendicular lines, and special segments of triangles and other polygons. GEOM.2B Derive and use the distance, slope, and midpoint formulas to verify geometric relationships, including congruence of segments and parallelism or perpendicularity of pairs of lines. GEOM.2C Determine an equation of a line parallel or perpendicular to a given line that passes through a given point. SO1.1: SWBAT apply prior knowledge of coordinate systems to place geometric figures on a coordinate plane for analysis. (GEOM.7A) SO1.2: SWBAT determine the relationships between pairs of lines and figures using slopes and their equations of lines. (GEOM.7B) SO1.3: SWBAT find characteristics of segments that determine the relationships between segments. (GEOM.2B) SO1.4: SWBAT write the equation of parallel and/or perpendicular lines given a line and a point. (GEOM.2C) SO1.5: SWBAT adapt equations of lines writing when necessary to use point-slope form.
