Teaching the visual structure of algebra through dynamic interactions with no...

2017 (see original presentation & discussion)

Grades 6-8, Grades 9-12, Undergraduate

Our video will showcase Graspable Math, a dynamic algebra technology tool designed for teachers, students, and anyone who wants to play and explore math within a fast, fluent, and conceptually grounded algebra system. This novel technology allows users to interact with algebraic structures in new ways. First, we allow users to manipulate and transform algebraic expressions with a touch of their finger or mouse, using gestures that are fluid and relatively error-free. Second, we allow learners and teachers to explore strategies and pathways through algebraic interactions and fluidly connect algebraic situations to other kinds of graphical representations. A final novelty is that because this tool has been built entirely in html 5 / javascript, it is web-ready, can be used on any device, and can be integrated into existing software. This video will highlight three use cases already deployed in schools, including a sidebar extension for Chrome,  a ‘whiteboard’ tool available on our website (graspablemath.com), as well as an elementary and middle school game-based application, From Here To There.
