4Combining scooped-out die-cuts with raised, shaped elements, two new TouchThinkLearn books offer youngest learners an irresistible opportunity to explore their universe in a hands-on, multisensory way. See the image, trace its shape, say its name: these modes of perception combine in a dynamic way to stimulate understanding of essential concepts. Experience the number "2" both by counting a pair of raised car wheels on one side, and feeling its shape on the other. Featuring a format unlike any other, these groundbreaking books translate abstract thought into tangible knowledge.
