This department shares the thinking of middle school students as they explore and communicate mathematics. It will highlight students' work, including projects, investigations, or creative solutions to the problems in the monthly menu. Original student work will be included along with sufficient information about the activity so that readers can try the same ideas with their students. Please send articles and information for “The Thinking of Students” to the editor of the department: Karen Higgins, 28669 Royal Avenue, Eugene, OR 97402; home telephone (503) 688-1759. If readers need additional information, please include name, home address, home telephone number, and school name with the article. Please submit slides or photographs when possible. Submissions do not have to be in polished form, as the column can be written from the information the editor receives.
