If you have ever gone to story time at the library, or if your child goes to preschool, you should be familiar with felt boards. They are a great learning/play tool for kids. You can use them for so many things: like telling a story, demonstrating shapes and sizes, as a place for dress-up dolls, or for counting games and learning letters. The possibilities are endless. Basically, they are both a great visual and hands-on learning aid for a wide range of ages and developmental levels. If you ever want to see examples of felt boards, just google "felt boards" and you will see a bazillion examples.
Going off the concept of a felt board, we made a felt Christmas tree! I just cut out the shape of a Christmas tree out of a big piece of felt (you can get felt at any craft store) and tacked it to the wall in Adoration's room. I cut a star out and some circles for the "ornaments." You could go fancy and make more intricate ornaments (especially if you like to sew,) but I just kept it simple. And there you have it: a toddler friendly Chirstmas tree.
Adoration has loved playing with it, "decorating" and "un-decorating" her tree. Whenever she tries to take ornaments off our real tree, I say, "let's go play with YOUR tree!" Then I redirect her to her room, and we play with her tree for awhile. It actually works pretty well! So not only is it a fun activity, but a distraction from tearing all the ornaments of our tree. ;) To extend the learning elements, emphasize the shapes and colors during your child's play. Happy decorating!
