The letters are not taught in an alphabetical order, and are grouped to reflect their use through the teaching process - the first group s a t i p n, for example, can be used to make more simple three-letter words than any other six letters. The two-letter sounds (''digraphs'') such as th and oo which can make two different sounds are presented in slightly different forms. The letters b and d are also taught at separate stages, as these are a common source of confusion for children. Sounds that can be written in more than one way are taught in their simplest form first, with alternative spellings being introduced later. | The letters are not taught in an alphabetical order, and are grouped to reflect their use through the teaching process - the first group s a t i p n, for example, can be used to make more simple three-letter words than any other six letters.
