There are increased calls to incorporate technology into classrooms, which have led to the adoption of the iPad® in many classrooms around the country. This tablet computer is often chosen as the medium for technology integration because it is user-friendly, lightweight, and wireless. It also allows access to inexpensive applications. Although iPads may be considered expensive, they afford access to online textbooks that can be updated annually, thereby reducing costs over time.

Here is a simple way to turn an ordinary whiteboard into an interactive tool that allows students to design and build pathways along which a sliding object will flow—within certain constraints—to reach its final destination. Students must reason, conjecture, test, conjecture again, and then retest their design features to determine a solution to the presented investigation.
