N2 - Constructing and reasoning about covarying quantities is fundamental to students’ modeling of dynamic phenomena. In this report, we describe how we designed and leveraged 3D-printed manipulatives in parallel with iterative task re-design to support middle-grades students (ages 10-14) constructing and reasoning about covarying quantities. We present data from a design experiment to highlight why we adapted the original task to incorporate 3D-printed manipulatives in order to support students’ constructions of mental images of quantities in ways consistent with researcher intentions. In doing so, we highlight how 3D-printing has opened up new possibilities for manipulatives in mathematics education.
