My post of Advent Activities for kids has proven to be the most popular one I've ever written, so I thought I'd try one giving Christmas activities for kids--and focus on the Christmas that features the baby Jesus, the stable, and the star rather than the one that features Santa, the reindeer and Frosty.
Apples4theteacher appears to be a site designed for teachers and has coloring sheets, poems, songs and more. It looks like there is quite a bit here, but you have to hunt a little.
Coloring Book Fun has coloring pages for a lot of things, including religious Christmas pages.
Resources for Catholic Educators links to coloring pages too.
A Google search for Christmas coloring sheets will give you lots of options, but check them out before turning the kids loose--some are anti-Catholic.
CatholicMom has lots of ideas to keep the little ones busy.
Catholic Culture gives us Christmas morning prayers and evening prayers.
Catechetical Resources, from the publishers of the Faith and Life religion books give us Christmas activities for the brain as well as fun things to do.
Check your child's grade on Sadlier's website and find a Christmas activity for his/her age group.
Preschool kids will like this site.
Domestic Church has several Christmas activities.
The ladies over at Catholic Cuisine are bound to have something good to cook for Christmas.
The Daughters of St. Paul have some online activities for kids.
Of course the most necessary part of celebrating Christmas is celebrating Sunday mass with the community. The web gives us lots of resources to help children understand the weekly readings. The publishers of the Faith First religion texts have weekly summaries, discussion topics and activities based on the readings. Sadlier has a similar site. Catholic Mom.com has coloring pages, worksheets, lesson plans, and more for each week. Open Wednesday has a variety of activities as well.
