Overview

This part provides a review of the Learning Trajectories for length, area, and volume by acting out scenarios involving students at various levels of each Learning Trajectory.

Key Points

Learning Trajectories provide specific language to describe students’ thinking about measurement. This language can be used to describe what students understand and can do at any point in the Learning Trajectory, which supports a focus on students’ specific strengths rather than on their deficits (i.e., what they do not understand or cannot do). The names of the Learning Trajectory levels can become helpful tools for interpreting students’ thinking.
