IX. Class 12

A. Participants focus on investigations focusing on Coordinate Geometry

Participants should choose investigations that involve:

• Determining whether lines are Parallel or Perpendicular
• Finding the length and midpoint of line segments
• Finding the distance between two points

A. Explore Coordinate Geometry Investigations

• Comparing Lines
• Intersecting Circles
• Forming a Square
• Quadrilaterals Inscribed in Quadrilaterals
• Circling the Coordinate Plane
• Twice Reflected Over Parallel Lines
• Finding the Midpoint
• Medial Polygons
• Equidistant Chords
• Maximum Quadrilateral

B. Each participant creates a technology-enhanced mathematical investigation for their own classroom
C. Participants add middle school lesson plan to their online portfolios
