A quote from the website:
“When asked ‘What is the first thing you should teach a child when they are learning to read?’ Most people reply “the alphabet.”
“But there are in fact a few steps you can introduce to your child before and during the more formal instruction ofteaching the alphabet letters! You are most likely teaching these steps without even realizing – but it is good to be aware of them to help give structure to your play times together so you will instinctively know when it is the right time to move onto the next level. This ‘pre-reading’ time is often referred to as Phonemic Awareness (P.A). “
