One thing I constantly work on as a parent is figuring out how to help my children motivate themselves to do things they find difficult. This marble jar has proven quite useful. Marbles are added to the jar every time the kids do something especially helpful or kind. Sometimes they know in advance that they will get to add a marble to the jar if they complete a particular task, and sometimes I add it without telling them in advance. We go days without adding marbles sometimes, and other days they put several marbles in the jar. When the jar is full, we’ll all go out to dinner – the choice of a reward that the entire family will enjoy has replaced previous competitive issues with a much more cooperative atmosphere! Sometimes Johnny and Lily choose to play with their marbles before adding them to the jar, which is also fine!
