What is Synthetic Phonics

Synthetic Phonics is a methodology to teach how to read and write the English language is a systematic way. The centre of Synthetic Phonics is the sound-spelling correspondences which are sequenced taking into account the 44 sounds of the English language and the different ways to spell them. These sounds are divided into short and long vowels, diagraphs and triagraphs and the rest of the sounds. This way of naming the different kind of sounds is used in the National Curriculum in England of September 2013. It is included in a systematic way of teaching the written code of the English Language. This systematic and phonological approach helps students to learn step by step all the regularities and irregularities of the English writing. 
Thanks to this approach to reading and writing, the English language becomes easily codable and decodable from de begining and its pronunciation is deeply learnt.
