I am a Early Childhood Special Needs Teacher and I have to say I have never seen anything like this. It's amazing! My daughter bought it and taught my granddaughter, M'kaela, to read at 3 years, she is now in kindergarten and will be 6 in January and she is at a 3rd grade reading level.
My daughter is currently teaching her second daughter, that is 3yrs & 6mths, along with 2 other children that are in her home day care one 2yrs & 9mths and the other 2yrs & 3mths. I also have to tell you that her second daughter, has had 5 brain surgeries, 4 for hydrocephalus & 1 a stage 4 cancerous brain tumor. She has had speech therapy, but now is learning to read, her progress is a little slower but she is doing it. Anyway, I got off my subject, Being a Early Childhood Special Needs Teacher, I have decided to try it in my preschool classroom. The classroom is small 7-8 children total, but I never have them all at one time. I can't wait to get started and see how this works, in the classroom setting. I already work on phonemic awareness & phonics this will surely teach me something new that I'm not doing.
