[senco-forum] Wave 3 intervention

I am a primary SENCO in a one form entry school. I am currently looking to
collect a list of available wave 3 intervention programmes for literacy and
any recommendations for what really works. (I know that this varies for
every child but at the moment I feel as if I'm  constantly re-inventing the
wheel). I also want to start a wave 2 intervention at the beginning of year
one as an early intervention to gently  support children who seem to be
having difficulties in literacy. I have heard the "5 minutes a day" is very
effective. Any suggestions?
