My son has been really lucky, he has had an excellent reception teacher and has been taught how to read properly by synthetic phonics. His teacher followed Jolly phonics logically with great results.
He has a little friend who is at a different school. She is 6 months younger than my son and has had only 2 terms of school. This girl has been taught to read by sight words and a reading ladder. Because she started after christmas she got taught the letter sound "ch" before being taught "s", "a", "t", "p", "i", "n".
The result is that this poor little girl is still on Oxford Reading Tree level one and hates reading. Her mother is convinced that her daughter is dyslexic because the little girl is extremely bright in other areas of the reception curriculum. I think the reason the little girl can't read is that the teaching she has recieved has been a mess.
