This drag-and-drop exercise brings to life the formula for
the area of a triangle. Not only does the exercise encourage
the student to interact with the material through drag-and-drop,
but the content has been constructed in a way that underscores
the key relationship in the formula. If a student forgets
that the area is one-half of the
product of base and height, he or she will immediately see
the mistake and understand the pattern of halving the product
of base and height. This lesson is accomplished without any
textual explanation" the student comprehends the formula simply
by interacting with the information on the screen.
