1. 3-D Object Viewer - Students may explore a variety of 3-D objects and their accompanying 2-D views. or
2. Bisection - Understand and learn how to construct points, segments, and rays of bisection. Work through the lesson, experiment with the interactive figure and then answer ten questions [caution: do not submit until you have selected answers to all of the questions] and
3. Building Houses with Side View - student constructs a block figure (dynamic, perspective drawing) to match (10 different figures) or
4. Coloring 3-D sides - [UK spelling on this site] Find the red sides shown in a series of 2-D drawings and click on the right face of the 3-D model to color it red. 20 questions or

6. Guess the View - Students are given a 3-D view of an object, and then given a 2-D view of the object. Students must choose which of 6 views is being displayed from a list. and
7. Plot Plans and Silhouettes - from Shape and Space in Geometry - the student task is to come up with plot plans that could match the given silhouettes. Background information is available at another page.
8. Pyramid Panic - [a geometry game] Apply increasingly-complex rules of geometry to help an imprisoned Mummy build pathways out of its pyramid prison and escape from the jaws of a hungry Egyptian demon
9. Quick Images - In the following Interactive Activity, you'll stretch both your visualization and drawing muscles. (click on Show Shape to begin the activity)
10. Rotating Houses - Students are presented with a 3-D figure created with blocks that can be rotated and flipped using a mouse. The figure must be rotated until it matches a 2-D representation of one of the views. or
