Nurturing the Natural Curiosity of Children! Research shows that children are innately curious and want to figure out how the world around them works. Teachers or parents do not have to force children to become curious or learn. They just have to follow a child's lead and help him or her learn about the world. Curious Kids is created with this thought in mind and would enable children to learn and grow while having fun. There are eight books in this series for grades 1 to 8.
