Organize a park playdate
You might be tempted to avoid the outdoors due to the cold weather, but it’s actually fun for the kids and their friends to get some outdoor exercise. So organize a park based playdate and break a big thermos of hot chocolate and cookies to share afterwards.
Organize a field trip
Call your local Parks and Recreation department to find out whether they offer free tours for local parks. Often Parks and Recreation staff tends to have some downtime because it’s not the hot busy summer season and will be able to assist you. If not, they can make great recommendations on what books are available in the library for you to be your own tour guide for the kids.
Go to the library
Visit the local library and find out if they offer any story time or activities for the Christmas Break. If not, the library usually has a public bulletin board for you to post your idea of a get together. Often the local library has a community room that you can use for free to organize fun and free activities for your kids.
Host a teaching session
Get your neighborhood friends together and organize a teaching session on some fun topics for kids (each parent can take a topic to research and to teach the kids).
Get your kids to volunteer with you at the local zoo (if you are a volunteer, you don’t have to pay for admissions). Often you have some downtime when you volunteer at the zoo, so you can use the downtime to enjoy the zoo with your kids.
Choose an eco-friendly theme for the day or week
If your kids are really interested in a certain topic (e.g. water conservation), then, research and borrow a book in the library to find out more about it. Then, contact your local water council/department to arrange for a free tour. Often they will provide some free souvenirs as well.
