Preschools may just look like a jumble of toys, books, activities etc, to the uninitiated, but in reality, they are very carefully planned to stimulate your children's interest and motivate them to explore and discover.
They are geared towards fine honing children's conceptual skills, to prepare them for learning to read and write, to count and figure. They're also set up to give your children that wonderfully creative but incredibly messy play that's essential to develop the finer muscles and coordination they will need to launch successfully them into the world of learning.
For those whose children are about to begin their education, here is a great description of what to expect when you first visit the preschool. Read THIS and look for similar organisation in your child's preschool.
