These sets are perfect for delivering just the right amount of tactile input for reinforcing correct formation and identification of letters and numbers. The specially formulated tracing is not too rough & scratchy, allowing for repeated use without irritating skin but not too soft & smooth as not to leave a sensory effect. Cards are a generous 4”x5” with green dots indicating where to begin tracing and red dots where to stop. Directional arrows teach correct letter/number formation. Each set also includes multisensory activities for letter-sound recognition and instructions in English, Spanish & French.
