Amazon.com description: Product Description: Featuring spreads each with raised shaped objects that fit into scooped cutouts on their opposite page, these two new TouchThinkLearn books offer the youngest learners an irresistible opportunity to explore their universe in a hands-on, multisensory way. Seeing the image, tracing its shape, saying its name: these modes of perception combine in a dynamic way to stimulate understanding of essential concepts. Discover—and experience—a pig by tracing its raised outline on one side and the concave form of the mud puddle it wallows in on the other. Clusters of related words on each spread offer parents and children a springboard for further conversations to encourage the language skills so crucial to later successful learning. In a format unlike any other, these groundbreaking books translate abstract thought into tangible knowledge.
