Flannelboards are wonderful tools to use with young children. Personally, I love them. Here is the one I made. I took a piece of plywood, cut out some flannel to wrap around and then used a staple gun to attach it. I've also seem smaller ones using a cereal or cracker box. I am thinking of making a couple of those for my boys to use at church or in the car or something of that nature. You can use felt, sandpaper, flannel, velcro, or anything else you can think of that will stay on flannel to put on the backs of the pieces. You could even just put a little tape on the back if you don't want to put anything permanent on them. I love using flannelboards for stories, games, songs, and anything else I can think of.
Here are some links to some great printables:
Also, please vote on the poll I have on the my rightside tool bar. I'd appreciate it. Thanks. :)
