Your little one will enjoy these over-sized manipulative blocks as they engage in active play. This is a great way to introduce children to key literacy skills they need to begin reading. Each rod measures 2 " x 2 " x 2 " and features a vowel or consonant and initial vowel picture or initial consonant picture on each side. The rods are sized perfect for small hands to grasp and are color-coded with an interlocking design. Young readers will learn how to identify and syllables, recognize and produce rhymes, isolate and match initial sounds and blend sounds to make words while developing an understanding of letters, words and sentences. Help build your child's self-confidence and get an early start on reading and literacy skills. There is also a classroom kit available with a Teachers Resource Guide and features more than 80 activities that correlate to Pre-K and Kindergarten standards. They also come in a convenient storage container.
