Pre-Kindergarten Math

Common Core curriculum builder and lesson designer for teachers and parents

In Pre-Kindergarten, instructional time should focus on two critical areas: (1) developing an understanding of whole numbers using concrete materials, including concepts of correspondence, counting, cardinality, and comparison; (2) describing shapes in their environment. More learning time in Pre-Kindergarten should be devoted to developing the concept of number than to other topics.
