As children play, they gain knowledge of how the world works and they find their place I the world. Construction experiences, like playing with blocks, strengthen the foundation of math, science, reading, and writing. Children also develop physical coordination, build self-esteem, and learn how to work with others.
There is no substitute for a good set of unit blocks. Many types of blocks are available, but the most versatile and durable for preschool and school age children are unit blocks. Unit blocks (and their big brother: hollow blocks) represent a financial investment for many programs. Although blocks seem expensive initially they should last for many years and in the long run actually cost only pennies a day.
