Described are many concrete readiness activities within ten broad categories that are designed to provide children with a solid foundation for mathematics and that help prevent learning difficulties in mathematics. Preschool mathematical experiences form the foundation for all studies in mathematics. Without a sufficient number of appropriate…

This learning module helps the teacher to master teaching skills that stimulate children to explore materials and to order their explorations in ways that lead to classification and that generate the child's own structuring of his discoveries and experiences. Teaching behaviors focused upon are congruent with Piagetian concepts about a child's…
