The shamrock is a symbol of Ireland. It is a three-leafed old white clover. The four-leaf clover is often confused with the shamrock. While the four-leaf clover is a symbol of good luck, the three-leafed shamrock is mainly an Irish Christian symbol of the Holy Trinity and has a different significance. It is also a common way to represent Saint Patrick's Day.

Preschool shamrocks to color are fun, but they also help children develop many important skills. These skills, eye-hand coordination, color concepts, picture comprehension, form the foundation for early learning success. Children who color generally acquire and use knowledge more efficiently and effectively.
