An Extraordinary Egg by Leo Leonni is the story of a trio of frogs who find a very large egg. The “know it all” frog tells the others that it is a chicken egg. They believe her because, “She knows everything about everything.”
I have used this story with second graders as well as with third grade transition students. My transition students needed practice answering questions in complete sentences by restating the question. An answer key is included, but I purposely wrote higher-level open-ended questions so any reasonable answer that is explained well would be correct. Enjoy!
