Technology for Mathematical Argumentation

Technology for Mathematical Argumentation, or TMA, aims to bring mathematical computation tools to early elementary grades in order to support students in learning and demonstrating algebraic reasoning. These tools are created in collaboration with leading mathematical educators at TERC, and are being developed and tested using our tablet-based software system called Classroom Learning Partner (CLP). CLP is also used in our NSF-funded project, INK-12: Teaching and Learning Using Interactive Ink Inscriptions in K-12. TMA makes use of two key CLP features: functionality that enables students to create animations of representational models, in particular visual models for multiplication and division; and functionality that supports sharing, classroom display, and playback of student work as the basis for class discussion.
