As someone with Masters degree in Educational Technology, I have done quite a lot of research, studies and writing on the topic of how important it is to expose children to technology in a way that is relevant to them. This great app is perfect to enhance a Preschoolers understanding of basic concepts of learning letters and numbers. My little guy loves to trace, so he especially enjoys the tracing exercises. It is vitally important to introduce these concepts in a way that is both educational and fun. When that occurs, children tend to more easily retain what they are taught. This app is a fantastic addition to our lessons and I love the fact that the kids are learning while theyre having fun!!
