The Rhyming Post Office helps young children learn to focus more closely on the sounds they hear in words all around them, and to discern differences in closely related words. Hands-on lessons follow a careful developmental sequence, progressing from simple CVC words with different initial consonants to more difficult discriminations, including rhymes with more than one spelling pattern. Includes 4 sorting mailboxes, 96 picture cards for 25 word families, card storage box with labeled dividers, and guide with developmentally sequenced lessons.
