Didax's popular Chunks game consists durable plastic tiles showing the most frequent onsets and rimes for practice and fun in word-building. Put the tiles face-down on a table and children turn over one of each to see if they made a word. Plays like " concentration" and develops power in phonics, spelling, word recognition, vocabulary development, and visual memory. A perfect classroom game for small groups and " centers" and ideal for family fun. Onsets are the beginnings of one syllable words and rimes are the endings of one syllable words.
