I did this when my kids were small, the youngest is now 32. I did it for my older grandkids, and I am now doing it for the younger grandkids and greatgrandkids. I have saved the colored plastic lids off of various bottles, such as mayonnaise, peanut butter, etc. Lids have to be too big to fit in a young ones mouth. I have a couple metal ones but most are plastic.
I keep them in a drawstring bag in basket, I use as a toy box for when the kids visit. They are good to teach colors, to count, to stack like blocks, to pretend, kids favorite is to pretend we are at a restaurant and the lids are food. Put little one between two larger ones and you have a sandwich, etc. Their imagination can run wild. So much fun with no additional expense. The amount of enjoyment for all is endless.

Editor's Note: As Knitter926 mentioned, make sure that the lids are too large to be swallowed by children under 3 years old.
Here is an easy craft you can do with your kids, and they can play with it afterward!
