Glue the feet and bill to the duckling's body. Add feathers, beads for eyes, or other decorations to complete your duckling. Have your students draw pictures of objects and characters from the story, then they can place them on a map of Boston. You may want to make a large-scale, simplified map of just the streets that are mentioned in the story. See a sample map.
Students can practice retelling the story and retracing the ducks' routes.
Have the students write each duckling's name on a file card, then scramble the order of the file cards, and practice putting them back in alphabetical order. See if the students can think of new names for the ducklings that mirror the same alphabetical sequence. This story takes place in a city and your students will be able to find urban characteristics throughout the book. Make a chart which highlights the characteristics of and differences between a city, a suburban area, and a rural area. Students can compare and contrast the buildings, open spaces, transportation, population sizes, etc.
