Behold the Fold app for iPhone and iPad

Behold the Fold is a mental paper folding activity. You are presented with a "paper" layout of a flattened cube. This layout can be folded into a six sided cube. On different faces of the cube are three colored dots and an arrow. The goal of the game is to fold the cube in your mind to determine which dot the arrow is pointing to, either the red, blue, or green dot. Then select the correct button to answer.

Math skills that are practiced through using this app include:

* creation of 3D objects from 2D nets
* geometric construction
* mental paper folding
* mental rotations

This app is best for users 12 years of age or older and may have special appeal to adults who like exercises that challenge ones spatial abilities.

For researchers interested in the thinking behind this app, the game idea was inspired by the work of Shepard & Feng (1972) and evolved with the help of a modified mental paper folding exercise developed by Brannon & Lorr in a research paper by Greenfield, Brannon & Lorr (1994). This app uses 11 nets without reflections and all "roll ups" have been removed. Unlike the Brannon & Lorr exercise, all questions asked have a solution that is either red, blue, or green, with non-match solutions removed. The complete "deck" of unfolded cube layouts consists of 72 visual examples, which upon completion randomizes itself with a fresh deck of 72 examples. Each display of a flattened layout can appear rotated on screen in one of four different orientations; 0, 90, 180, or 270 degrees. This exercise was developed to have no end.
