The Proportioner is designed and developed by the Concord Consortium. The software employs a "paint" metaphor to examine relationships in dimension between an object and scaled models of that object. Users can examine proportions among linear measures as well as area measures that are proportional to products of linear dimensions.
Innovative technology developed by the Concord Consortium permits networked users of our software to save with one click an image of any screen made with CC interactive software. They can then share their work with other networked users in real time or asynchronously.
