Volunteer for community projects. Join the PTA, attend town meetings, sit on town boards. Make sure your children are aware of the good citizens around them. Good citizens participate and help in their local communities, care about their neighbors, and participate in the democratic process. Good citizens might, for example, volunteer to help the elderly or less fortunate, speak out or take action to correct community problems, and organize or participate in community cleanup days, raise money for charities, encourage people to vote.
Research shows that good habits begin early.
Use your opportunities to talk to even very young children - teaching them about democracy and pointing out good citizens. Read newspapers and magazines. Watch the news. Encourage your children to do this also. Talk about things.
