Contrary to popular belief children can use play and learn to read at an early age. The Lego foundation has researched play and have identified it as a continuum. At one end there is child lead free play and at the other end there is adult designed direct instruction play.
The adult lead direct instruction play is what WordSmart is based on. You can view Lego’s research in their learning-through-play white paper.
