Ages and Timelines begins with the story of eight-year-old Carlos's visit with his great-grandfather. Carlos's fascination with his great-grandfather's beautiful silver hair, and the time it will take him to grow a similar mane, initiates a family-wide investigation into age differences. The context of age differences and the open number line model support the development of subtraction strategies.
