You've launched a pumpkin into the air. How can you calculate its average velocity? Viewers learn how to calculate the average velocity of an object from tables and graphs, including a careful derivation of units, in the first installment of a 13-part video series. The video then connects the idea of average velocity to the slope of the secant line.

Instructional Ideas

• Use this video during an introductory lesson on average velocity
• Pause video while pupils compute average velocities before moving on

Classroom Considerations

• Learners need to remember what a secant line looks like on a graph, as well as how to use the slope formula to calculate the slope of a line

Pros

• Resource uses different representations in computing average velocity (numerical and graphical)
• Includes variation in context and situations

Cons

• Membership may be required to view entire video
• Videos do not include any algebraic examples (finding average velocity from a given algebraic function)
