Touch and learn. Applying the tactile features of Montessori teaching, this innovative board book uses lightly grained sandpaper tracks to encourage children to trace the letters of the alphabet as they enjoy whimsical illustrations of each letter. One-of-a-kind colorful illustrations, sturdy board pages, and no moveable parts make this a unique addition to an early learning collection. About the Discovery Concepts series: Discovery Concepts books celebrate Montessori's curious discovery approach to learning. Maria Montessori believed "the hand is the chief teacher of the brain," encouraging students to learn by touch and created specially designed materials such as sandpaper letters to support this method. Inspired by her teachings, each book in the Discovery Concepts board book collection uses tactile enhancements to engage young children in discovering the topic at hand. Beyond the tactile elements each title is designed to capture a child's imagination and curiosity as they learn.
