The action research team developed a "Personal Math Concept Chart". This chart required students to describe the mathematical concepts that they were studying in the Geometry strand of Mathematics using their own images and words. In this study, students were encouraged to express their own understanding of geometric concepts in order to strengthen their own personal knowledge. The purpose of the Personal Math Concept Chart was to enhance students' ability to express themselves using mathematical terminology. As part of having students work toward improving their mathematical expression with the Personal Math Concept Chart, the teachers on this action research team invited students to connect the concepts learned in class to everyday applications.
