Twenty-five outstanding middle grade mathematics teachers were selected by the staff of the Middle Grades Mathematics Project (MGMP) at Michigan State University to participate in an Honors Teacher Workshop during the summer of 1987. During the final week of the encounter, 50 colleagues joined the workshop. The participants came from 20 different states and represented a cross-section of the best mathematics teachers throughout the nation. A major focus of the workshop was the development of instructional leadership. The potential for leadership weighed heavily in the selection process. The effects of the workshop will be assessed in a follow-up poll in September, 1988. This document contains general information relative to the workshop, as well as 14 presentations: "Critical Issues in Middle School Mathematics"; "Destroying Boxes"; "Some Issues in Teaching Secondary School Mathematics"; "Problem with a Purpose"; "Teaching Math with Manipulatives"; "Probability"; "Changing the Negatives to Positives: Transforming General Mathematics Classes"; "Gender Bias and Negative Numbers"; "Proportional Reasoning"; "Math Anxiety"; "Teaching Gifted and Talented"; "Algebra"; "Mathematical Paradoxes in School"; and "Equations."
