There are lots of ways that kids and families can volunteer:

• Visit a nursing home and offer to play games with, read to and just visit with their residents 
• Organize a clean-up day to clean up a park, school or even a lake in your town 
• Check with your local hospital – they often have programs where kids can help cheer up patients
• Animal shelters always need volunteers to walk pets, and help clean and care for them, and even to foster them 
• Get together with your friends and gather up old toys and books to donate to libraries, shelters or churches 
• Organize a can drive to collect food for shelters and food banks  You can also collect coupons and donate to food banks, or help with a food drive 
• Tutor younger kids
• Help elderly neighbors with yard work or by shoveling their walk
