Developmental psychology studies show that early mathematical skills are decisive for children in their later performance in school. But what about children who display particularly gifted talents?Mathematically gifted children display a special interest in everything to do with sizes, forms, numbers and quantities. The normal stimuli of nursery school rarely suffice for them. But how can one properly support these children in their development? The materials gathered in this volume offer a multitude of scientifically evaluated tasks that provide learning conditions corresponding to the personalities and abilities of such children and foster their special gifts. Particularly preschool children will benefit from the direct confrontation with mathematical matters that will motivate them to use and display their potential.
