The other day after I laid the baby down for her nap, I started dumping things into a large cake pan. Peanut who is 3 1/2 years old was instantly curious as to what I was doing. I just kept dumping and finding things.
I then presented the cake pan to her and a bunch of small bowls. I told her she could look through all of the loot and sort it. She had a splendid time sorting and worked on this activity for some time. If you are looking for a quick activity for these LONG winter days, this one works great!
