The booklet contains step-by-step play and learning templates for children from about 4 years old. Children's perceptual skills develop differently, so the exercises may be suitable for use earlier or later. Give the children the time they need to engage with the content without feeling overwhelmed. The play and learning templates train numerous aspects of visual perception and enhance children's thinking and problem-solving abilities. The transition from concrete images to graphic objects expands and structures children's visual habits and promotes their concentration skills. To work with this exercise booklet, you will need the miniLÜK solution device.
