We read Five Little Ducks and acted out subtraction problems using duck puppets. Then we used rubber ducks in a "pond" to model subtraction stories. I modeled with the ducks while the kids used orange cubes for ducks and blue construction paper ponds.
Once upon a time, seven tiny duck beaks pecked their way out of their eggs, but the eighth egg was a little bit different. What emerged wasn't a duck at all--he was a dinosaur! Everyone notices how different he is. He doesn't waddle! His teeth are too big! Feeling ugly and outcast, the dinosaur duckling leaves his family and ventures out on his own.
• PICTURE STORY BOOK- Farmer Duck by Martin Waddell. A duck does all of the yard work for a lazy farmer. The animals get together to run off the farmer. This story tells about teamwork and problem solving. Would be good to teach this to upper elementary.
