This one-semester survey course introduces students to:
- basic ideas about geometric shapes,
- how we use numbers to define and describe them,
- how they relate to one another
Students use The Geometer's Sketchpad software to explore geometric concepts and make discoveries. Topics covered include angles and angle relationships; parallel and perpendicular lines; transformations, symmetry and tessellations; coordinate geometry; triangle relationships; quadrilaterals; polygons and polyhedra; Pythagorean Theorem and special right triangles; circles; perimeter, area, and volume; congruent triangles and proofs; and similarity and trigonometry.
Course materials: The Geometer's Sketchpad software; online readings from a variety of sources; teacher created notes, videos and tutorials.
Standards met: This course meets all standards and benchmarks in the Geometry & Measurement strand of the Minnesota 2007 Math Standards for Grades 9-11.
Honors Opportunity: No
Prerequisites: None—this course is particularly appropriate for students who do not have the time in their schedule for a full-year sequence. It is important, however, for students to consult with their counselor regarding number of math credits as the year-long Sketchpad Geometry A and B course may be a better option.
