Description:

This iOS app is an open-ended tool for exploring a variety of mathematical topics. Learners stretch colored bands around pegs to form line segments and polygons in order to make discoveries about perimeter, area, angles, congruence, and fractions. Users can switch from a 25-peg board to an expanded 150-peg board and fill in the interior of shapes with transparent color.
