Geometry: 2D and 3D Figures
In Geometry: 2D and 3D Figures, students explore the terminology and properties
of threedimensional solids. They visualize solid figures, learn
the names of their parts, and build and draw figures in two and
three dimensions.
Participants in this course:
 Examine the
development of student geometric thought, using the four levels
of abstraction defined in the van Hiele framework (visual, descriptive/analytic,
abstract/relational, formal deduction and proof).
 Consider
ways to support studentinitiated inquiry in a classroom.
 Examine questioning
strategies that support concept clarification, reflection, and
discussion.
 Explore
how activities such as making models or writing geometric puzzles
can reinforce students' understanding of geometric figures, and
provide a way to assess students' geometric thinking.
 Reflect
on their own understanding of geometry.
