This sounds like a really exciting idea, as well as something that would be feasible to implement in. From my experience of working in kindergartens in Ghana, schools tend to be extremely resource poor whilst many of the phonics programmes already out there are very resource heavy, thus making them out of reach for the vast majority. This idea can solve this problem- a problem that clearly needs to be solved.
From the early stages of implementing a phonics programme in kindergartens in Ghana the results have been amazing. The P1 teachers are singing the praises of the KG teachers about how well their students can read and write- and in fact the teachers believe they are already achieving more than any of their past students ever have.
This idea has the potential to positively impact hundreds of thousands of children- a very exciting thought!
