When the students in your family can't see themselves getting their homework done, ensure that there's no excuse for seeing clearly. Carrots, which are famous for contributing to good eyesight, have a lot more than vitamin A going for them. They are a pure and natural source of energy and antioxidants to keep that kid healthy and feisty for years to come.
In "baby" form, carrots can be quickly and easily packed into baggies for lunches. After school, a bowl of baby carrots and some low-fat dip will disappear faster than homework next to the dog -- the dog is really responsible for that homework fiasco, right?
