Elkonin boxes - a teaching device used during phonemic awareness instruction to support the sequence and number of sounds the student hears in a word. When working with words, the teacher can draw one box for each sound in a target word. Children push a token into one box as they say each sound in the word. Elkonin boxes can also be used in phonics instruction to support phoneme-grapheme mapping. Named for a Russian psychologist, these are sometimes called sound boxes.
