iWorldGeography colors match American Montessori Society classroom materials.

iWorldGeography Series blends self-correcting, child-directed-activity design with Geography curriculum used in Montessori Children's House and Lower Elementary classrooms. Concept and visual design is thoughtfully integrated to supplement existing curriculum and classroom materials. The series was inspired by 3-year's observation in Lexington (MA) Montessori School Children's House classrooms where MyWorld, TenSun's desktop-based version of this series, has been used since 2004.
