Give an overview of stack structures. If possible provide the class with examples of good stack design. Tell the students that they will be responsible for linking a card to a relevant Web site of their choice. They should keep this in mind while conducting their research. The multimedia project moves in a linear path.
Navigational buttons allow the user to move forward or backward throughout the stack.
A hub structure is like a bicycle wheel where all of the spokes come together at the center. Like a tree, this is the most likely structure to use when assigning a cooperative class stack. Introduce the class to the role of a storyboard. A storyboard serves as a blueprint for the framework of the stack. The storyboard provides a work space where the team can plan the structure of their stack as well as the images and text for each card.
