    discuss the featured career in your student’s math book. At the
    end of the unit you and your student can further explore this career
    through the Math in Career Activity on the Unit Project page.
    There are also many exciting online resources available to you and your student including
    Math on the Spot video tutorials, Personal Math Trainer, and Animated Math activities.
