Students struggling to read

I have been supporting Kindergarten with reading groups and there is a small group of students who are slowly developing their reading and writing skills, that get daily support through a structured programme, but I feel they can gain more with one on one intervention. So I am going to devise a program that targets each students specific needs and is multi sensory. I will do a pre-assessment and review in 5 weeks time. This will also need to be implemented in the prekindergarten programme as their are some students who are struggling to learn their sounds. I am hoping that by intervening now they will be successful next year when they go to Kindergarten.
