# Exemplar: Remote Control Car Race (for staff mtg)

Lesson objective:

Understand that the same data can be represented in related tables, graphs, and equations, and that graphs and equations give more complete information.

In this Guided Collaborative Task, students will use their knowledge and understanding of proportional relationships to predict which remote control car will win a race. Students will figure this out by analyzing practice times and distances for two cars.

Under the “Additional materials” tab, you’ll find a "You're the expert!" handout that may be used as students work with a variety of representations. You'll also find blank graph paper there. Handouts are not required, but if used, each student should have their own.

Prior knowledge needed:

Students bring prior knowledge of graphing points, writing an equation to represent a linear relationship, and working with times and distances to find speeds. This prior knowledge is extended to comparing across these representations and describing the connections between them.

How students will collaborate:

Collaboration happens through a collaborative structure called "You're the expert!". Students will each become an expert on one of three representations of the given data (a table, a graph, or an equation) and will ensure that all members of their group understand how the representation works and helps predict the winner of a race.

Mathematical practice featured:

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they use multiple representations, including graphs and equations to reason about the relationship between given times and distances.

Key vocabulary:

- constant rate of speed

Special materials needed:

-graph paper (optional)
