To date, no child using the program in a classroom setting has ever failed to learn to read or to write.

Reading with enjoyment. Writing creatively. Decoding Chart - LEVELS The ninth of the Fourteen Apps The Decoding Chart converts words written in sounds to words written in letters.  It is the vehicle for transitioning the child from sounds to letters.  Its use is introduced once the child can comfortably read and write phrases. The Chart contains the pictures of all forty-four sounds arranged in the same rows and in the same order within each row as they are in the Stamping app.  Beneath each sound picture are various ways that sound may be spelled.  The spellings listed beneath each sound appear in order of frequency of occurrence in the words which beginning readers are most likely to encounter. Each of the spellings that appear beneath the sound pictures are color coded.  The first spelling of each sound is coded white.  If a second spelling is listed, it is coded yellow.  Third spellings are red, fourth spellings are blue, fifth are green, sixth are brown, and seventh are purple.  The color codings indicate to the child which spelling is to be used to write the letters for a word. The Decoding Chart does not contain all possible spellings for each sound.  It does, however, contain the spellings that appear in ninety-five to ninety-eight percent of the words the child will encounter while learning to read and write. A parent guide to how to use the Decoding Chart is included in The Guide instructions for the Writing Worksheets.
