Racial bias and racism can be a hard subject. It's tough for many adults to talk about, but how do you discuss that with your children?

Dr. Donald Easton-Brooks, Dean of the College of Education at the University of Nevada, Reno, says racism is something that needs to be talked about, even with children. 

"If we don't do it, society will do it for us, if society does it for us, society won't teach our children the values we want to teach them," he says.

He also says non-verbal cues are important. For example, if parents get tense or nervous around someone, kids will tend to repeat that behavior. Teachers have to learn to teach differently, because every child brings different levels of experiences. He also says there is no minimum age to start that conversation -- it could be as early as three years old. Historical events and holidays could also serve as teachable moments. 

"We get engaged in our family and family culture history so much, sometimes we don't explore those things outside our culture, so it's important for parents to expose kids to what the world looks like, because the world is getting smaller and smaller," says Dr. Easton-Brooks.
