For various reasons, my year 3 son has missed out on a good foundation in synthetic phonics - he can actually read very well - is keeping up with his year level - but his spelling is very poor. I think - due to his bad behaviour at the time (undiagnosed ADHD & ASD) - he missed those key years in reception and year one where the students focused on phonics. Could anyone please suggest a reading program that I can work with him at home to help him catch up? The school uses the read, write, inc program.
