These open response prompts, rubrics and solutions were developed by teachers enrolled in a 1998 Institute on Coordinating Geometry Concepts across Grades Four through High School, funded by the Dwight D. Eisenhower Mathematics and Science Education Act through the Kentucky Council on Postsecondary Education.

We think these ideas are valuable for sharing with other teachers. Due to time constraints, the teachers did not have the opportunity to field test these questions before submitting them for this booklet. Therefore, if you use these with your own students, you will undoubtedly find you wish to make some changes to fit the needs of your own classroom. Please feel free to use these in any way that you see fit.

All ideas and opinions expressed in this document are those of the authors and do not necessarily reflect the views of the instructors in this course, the Kentucky Council on Postsecondary Education or the Dwight D. Eisenhower Mathematics and Science Education Program.
