II. Class 2

A. Points, Lines, Planes, and Angles

Participants should choose investigations that involve:

• Identifying, describing and contrasting points, lines, line segments, planes, rays, and angles
• Describing and defining properties associated with points, lines, angles, and segments including distance, collinear, midpoint, congruent, bisector, interior/exterior, perpendicular, parallel, and intersecting
• Defining, estimating and measuring segments and angles

1. Participants engage in investigations dealing with Points, Lines and Planes
   • What is a Point
   • Balancing the Triangular Totter
   • Circling the Coordinate Plane
   • All Swimmed Out
   • Find the Hidden Treasure
   • Finding the Midpoint
   • Sum of Exterior Angles
   • Specific Slopes
   • Intersecting Circles
   • Constructing Quadrilaterals
   • Intersecting Chords
   • Intersecting Circles
     

B. Participants begin their first web-page write-ups to include in their online portfolios
C. Continued technological teaching and support (especially with GSP and the structure of a write-up)
