Egg twist letter matching surpise

I love all of the fun activities that you can make with plastic Easter eggs. There are so many out there on the web right now. I found this one last year and have been waiting to do it for a long time. I found it on Eager Little Mind. I got a big bag of plastic Easter eggs, counted out 26 and wrote each uppercase letter on one side of the egg. On the other side I wrote 5-6 different lowercase letters. The object is to twist the egg and match the uppercase letter to the lowercase letter. As an added bonus I found little toys, etc. to put in each one that start with that certain letter. They can open it and see what is inside after they've matched the letters. It would be ideal to have something that would actually lock until they matched the letters, but oh well, life isn't suppose to be ideal, right? :)
