I saw the idea for Discovery Stockings at Prekinders. You get some mini stockings (I used 5) and put an object in each one. I used a bell, an egg shaker, a mini present, a small toy, and a crayon. You let your child feel the object (I let K shake it too to see if it made a sound) and they try to guess what it is. This was a fun activity that was VERY easy to put together.
Here is K feeling one of the objects.
Here is his "thinking" face, as he tries to figure out what it is.
