ROUGH GRADATION TABLETS
Working with this material enables the child to recognise tactile characteristics of objects even without seeing them (blindfolded). Developing fine motor skills it is an excellent activity in preparation of writing. Like other Montessori materials for very small children, this material helps to develop concentration, will, intelligence and sharpens the observation of the environment. Working with definitions (smooth and rough) it gradually enriches the small child’s vocabulary. This material further refines the abilities developed by working with the smooth and rough boards (SE29).
