Help your child learn the sight words using Dr. Gary Brown’s DTT Words! Sight words are the first words that your child should learn to recognize. DTT Words includes 39 sight words for preschool children. Each word can be spoken by either a male or female voice, and then your child can select the word from a list of words shown on the screen. Additional word packs (kindergarten, first, second and third grade) are also available for purchase. This version also includes a free nouns demo pack. Future versions of this app will include the option of downloading even more word packs.
