I'm always looking for quiet activities to keep my kids reverent during church. More importantly I try to find things that are religious and quiet. I mean, if they're not going to be listening to the speaker then at least they can be coloring a picture of Noah and the ark or looking at pictures of Jesus instead of playing with a Cinderella doll, right?
Several years ago I came across these felt play books:

I think they're so much fun. The front cover contains a pocket that holds all the felt pieces and then each page of the book contains a large felt area where you can place the different pieces to create the story. A couple of years ago I decided that I wanted to get them for my kids. I found them at a Christian bookstore but they were $20 each! I needed one for each kid and $40 seemed liked a bit too much to spend on two quiet books. I haven't been able to get them off my mind lately and finally thought to look on amazon.com. Of course I found them there and they were only $12 each. That's more like it. I bought a couple and am going to be placing them in my kids Easter baskets this year. I can't wait to have them to bring to church with us.
Don't forget to check out some of our past Easter projects too:
