So drivers often consider alternative routes when planning a trip. However, a number of variables have to be factored into the equation before a decision can be made. Among these are the directness of alternative routes, the speed you can legally maintain on the routes, and the number of tollbooths and distance between them on the toll highway.
Students then invent similar problems with which to challenge classmates.
Learning Goals Determine the values of two variables in a simulated problem. Invent a similar problem for classmates to solve. Identify the variables involved in choosing a route to travel between two points connected by more than one highway. List the variables on the board. Discuss how each variable might impact the choice of route.
