We developed the Guide for Reflecting on Instructional Depth, or GRID, to help teachers reflect on their instruction, identify areas where they can be more student-centered, and select strategies to make incremental improvements in that direction. The four-part video series provides step-by-step guidance for determining students’ depth of mathematical justifications and who is driving those justifications.
