The basic character of a child is formed by age 7, so the preschool years are critical in shaping the future teenager and adult. Yet many parents leave their children with providers who they hardly know, and they do not know what goes on during those 8-10 hours each day while they are at work. We often don't know the parents of the other children or what influences those children may be bringing with them. I have become aware of numerous blessed children who were molested by older children in their home-day care situations. Of course we would never knowingly place our children is such spiritual danger, but it is often what we don't know that ends up being the problem.

Basic math begins with correlation such as counting out seven oranges or using a numbers board to count out 37 cheese crackers for snack.
