Virtual manipulatives simultaneously link representations with each and with students actions (Moyer-Packenham & Westenskow, 2013). Computers allow for algebraic, geometric, and symbolic representations to be displayed at the same time. This allows them to see relationships and make connections between the different representations (Shaffer & Kaput, 1999).
This manipulative displays algebraic, geometric, and symbolic representations of the slope-intercept form of a linear equation. As students make adjustments to the graph, they are able to watch the values and equation change on the screen simultaneously. This instant feedback allows them to view the concept from all angles to gain a deeper understanding.
