Tabula for grades 5-12 has dynamic geometry (DG) features similar to those in other DG programs. However, developer David Hartmann indicated it can be distinguished from them as follows: "1. It has a set of virtual manipulation tools for folding, cutting, and taping. This set is designed to help teachers guide and extend classroom activities involving paper, scissors, etc. Many teachers are familiar with Michael Serra’s Patty Paper Geometry book in which properties of shapes are discovered by folding and working with paper in other ways. Tabula can be used to model the steps in most of the activities. 2. It has a different approach to transformations that incorporates pushpins and animation. This is particularly designed to help students struggling with visual/spatial skills. 3. It has a set of virtual instruments that model their real counterparts. This includes a traditional compass, a safety compass, a ruler, and a protractor. Unlike models commonly used on electronic whiteboards, these instruments can be used directly in constructions and proofs. 4. It’s easy to use. The research suggests that DG software can be beneficial, but that in order to realize the benefits, a serious commitment to preparation and classroom time must be made. Tabula requires less of a time commitment and many of the same benefits." (personal communication, November 4, 2011)
