(The only preparation you need is to hide a teddy bear somewhere in the room.) Tell your students a story about a teddy bear that is lost and cannot find his way home. He should be hidden somewhere in the room, and students must figure out where he is based on the clues in the story. When they find him, they must bring him back home.
Once the students find the bear, you can finish the story by telling them that the bear was reunited with his friends and family and that everyone in the village gives your class many thanks and good wishes.
