Want to see better grades this school year? Send your child out to play. 

For more than a decade, studies have confirmed what our grandmothers knew all along: That physical movement increases blood flow to the brain and helps kids do better in school. In fact, children with ADHD see academic improvements after just a few minutes of daily activity – and could effectively treat some children without medication.

Here are four quick ways to get your child moving – and increase their brain power:

1. Limit sedentary activities such as television and video games.
2. Consider signing up for a sport or active class.
3. Initiate family activities, such as bike riding or swimming.
4. Encourage outdoor play, which naturally promotes activity as children play tag or climb trees.
