Experiments and theory on class inclusion,…

The activity of making a set of Logic Blocks is used to lead to a discussion of families of polygons and to questions about tessellations. (DT)

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…
