Phases of the methodology

The sequence to learn the different regularities and irregularities is the following one:

1st: basic sounds and only one way of spelling each sound. The order in which each publisher introduces the basic sounds may vary. In this site you can find one of the most commonly used sequence.
2nd: magic e rule.
4th: the alternative spellings of each sound should be learnt starting by long vowels.
5ththe alternative spellings of the other important sounds.
6ththe alternative spellings of the rest of the English sounds.
While learning each one of these things, reading and writing should be done, in order to practice each content.

Non-decodable words will appear during the previous phases and should be pointed out as words that don't follow any rule. After teaching the basic sounds it is interesting to work on them little by little to review their irregular spelling.
