One of the biggest ways that we learn is by playing. When you play, you learn as well, because it’s fun, and you enjoy doing it. This simple fact is at the basis of many of the activities that kids do at school, especially when they’re younger. School games are elementary for kids of young ages, because it’s hard otherwise to learn and to stay focused on a single topic.
Every method of teaching has been experimented with, and the one that proved the most successful was the one where kids were encouraged to learn by doing something they enjoy.
