Figure-ground perception, visual differentiation, size perception, shape constancy, as well as the perception of spatial orientation and spatial relationships, and hand-eye coordination: In early childhood education programs and during the first two years of school, visual perception plays a central role as a prerequisite for reading, writing, and arithmetic. The game series schubi®ToGo offers games that focus on essential areas of visual perception. Whether it's Martians and their UFOs, professional boats, or colorful deep-sea fish: children recognize, compare, and differentiate shapes, colors, figures, shadows, patterns, mirror images, positions, quantities, numbers, and symbols in exciting game variations and categorize them correctly. The themes of the individual boxes also provide a variety of opportunities for conversation.
