VI. Class 8

A. Participants engage in investigations of Polygons

Participants should choose investigations that involve:

• Classifying polygons according to their characteristics (e.g. regular, convex, concave, congruent)
• Solving problems about the area and perimeter of polygons
• Visually representing polygons using dynamic geometry software

Week 9: Engage in a variety of investigations of polygons and their properties

• Properties of Polygons
  • Medial Polygons
  • Two Squares
  • Arranging Toothpicks
  • Constructing Squares
  • Tessellation Restrictions
• Perimeter and Area
  • Restricted Perimeter
  • Apothem and Area
  • Triangle in Hexagons
• Symmetry and Diagonals
  • Symmetry Lines
  • Symmetry Lines 2
  • Round-Robin Tournament (Diagonals)
• Additional Investigations for Polygons
  • Inscribed and Circumscribed Polygons
  • Pentagram Triangles
  • Same Size Perimeter
  • Quadrilaterals Inscribed in Quadrilaterals

B. Participants continue to add to online portfolio

C. Discuss and brainstorm ideas about modifying the InterMath experience for a middle school mathematics classroom
