Another popular quiet book page is all about the beach: building a sandcastle! I found a great free pattern here. Because I wanted a quiet book with many different activities, but not too bulky, I reduced the pattern to have everything fit on one page.
As I was looking at similar pages, I stumbled across this one. The door of the castle flaps down to reveal a sewn on crab. It was so adorable, and added a touch of whimsy to the page.
When we are done playing, all of the pieces tuck into the sand bucket. Note the decorative seashells at the bottom of the page, which add just a bit more to the page.
This page primarily encourages imaginative play, however it does allow the kids to practice taking things out and putting them back into the bucket, and includes a flap that lifts down. There is also texture on the crab and seashells.
