Co-parents Jennifer Garner and Ben Affleck are trying to make their 'world a little bit better'

Jennifer Garner and Ben Affleck announced their separation over a year ago but they have always maintained the balance when it comes to raising their children; ten-year-old Violet, seven-year-old Seraphina and four-year-old Samuel.

Apart from spending time on helping out their children with their school projects, Garner told ET Online that she and the Batman actor are trying to make their 'world a little bit better' by being a better role model for the children.

"That's really important at home, to make sure that our kids know that we both have causes that we care so much about... that we dedicate time, resources, and our energy toward making our own little slice of the world a little bit better," she told the news outlet during the fourth annual Save the Children Illumination Gala in New York City on Tuesday (25 October).

The couple announced their divorce in July 2015 and vowed to maintain the "love and friendship for one another and a commitment to co-parenting our children." So far, they have maintained a harmonious relationship post their split and are often spotted together spending time with their children.

The Daredevil actress, who supports the Save the Children cause, also spoke about the importance of raising her children as the 'citizen of the world'. "It's so important that you model for your kids how to be a citizen of the world, and I think that's the very best thing you can do," she added.

The actress gushed about her association with the noble cause for children. "I've worked with Save [the Children] for the last eight years, and my whole heart is here. So obviously having all these people show up, it's the only time in my life where I see people with cameras and think, 'Thank you. I'm so glad you came. Thanks for coming."
