Skylersmommy is dead on: very common with gifted children. I remember one mother (on a different board) sharing about her son (in 1st grade) who stumbled on the idea of the need for fresh water and how the cost of a simple well was roughly $13,000.00. He had found his mission and started project after project from a lemonade stand to garage sale to many things in between so he could raise money to help dig a well. In a matter of a month he had collected over $1500. I thought it a wonderful project and if I remember correctly he took it to his class and they all got on board to take on the mission.
