The 60 Picture-Letter Cards, designed for use with Get Ready, Get Set, and Go for The Code, may be used for supplementary visual and auditory work. There are three types of cards, allowing for flexibility and a creation of a variety of games and activities. Picture cards provide a visual cue and match the key words in the Explode The Code student books. Letter cards allow students to practice letter identification and recognition. Picture-letter combination cards help students map sounds to symbols. Cards must be cut apart prior to use.
