Cynthia Nixon, currently filming "Sex In the City" in NYC, told People magazine this week that she is teaching her two children that you are never "too young to learn about giving back,"

The mother of Samantha, 11, and Charles, 4, helped launch of the Curél Lends a Helping Hand Campaign, which auctioned off celebrity hand prints to raise money for the American Red Cross.

"My children are being raised Jewish, so last year we all had a meeting with a rabbi, who said it's good to let your children know what their parents values are," said the Emmy and Tony award winner.

Nixon herself is a major advocate for public schools. Her partner, Christine Marinoni, works for the Alliance for Quality Education.

"My kids go to public school," she said. "I grew up here [in New York], went to public school, got a great education. It wasn't a tough decision."

Of her kids, Nixon said her daughter is "a very good writer" abd her son is "very into building and dinosaurs, that kind of thing."

Both have come by the set of the "Sex" movie: "If we're shooting late on a Friday night, they'll come by the set. They seem to be on set different days. But we talk to Charlie about James and James about Charlie, and one day we'll figure it out so they can be there at the same time."
