When Mrs. Mack says she will soon be a grandmother, her students realize that teachers have families just like they do! Suddenly everyone in the class wants to share information about his or her own unique family. Sarah tells of flying to China with her parents where they adopted her sister, Rachel. Christopher tells about his parents' divorce. They are still a family, but now he and his brother spend a few days every week at their dad's apartment. Nick lives with his parents, five siblings, and his grandparents--they need to order three large pizzas for dinner! And Hannah tells how she loves to garden with her two mommies.
