Title: Catching the Bank Robber

Grade Level: 6-8

Learning Intention: Students will be able to calculate the time and distance it takes for a sheriff to catch a bank robber who has a head start and a slower car.

Materials: - Whiteboard and markers - Calculator - Stopwatch or timer - Handout with the problem and space for calculations

Procedure:

  1. Begin by introducing the scenario to the students. Explain that the sheriff is chasing a bank robber who has a head start and a slower car. The sheriff’s car can go 180 km/hr, while the bank robber’s car can only go 150 km/hr. The bank robber has a five-minute head start.

  2. Write the problem on the board: “How long does it take the sheriff to catch the robber? What distance will they have travelled at that distance?”

  3. Ask the students to work in pairs or small groups to solve the problem. Provide them with a handout that includes the problem and space for calculations.

  4. Encourage the students to use the formula: distance = speed x time. Remind them to convert the units to be consistent (e.g. km/hr to km/min).

  5. After the students have had time to work on the problem, bring the class back together to discuss their solutions. Ask for volunteers to share their answers and explain their reasoning.

  6. If necessary, guide the students through the problem-solving process. For example, ask them to consider how far the bank robber can travel in five minutes at 150 km/hr, and how far the sheriff can travel in the same amount of time at 180 km/hr.

  7. Once the class has arrived at a solution, ask them to check their work using a calculator or by estimating the answer.

  8. Finally, ask the students to reflect on the problem-solving process. What strategies did they use to solve the problem? What challenges did they encounter? How could they apply these skills to other real-world scenarios?

Assessment: Assess the students’ understanding of the problem by reviewing their calculations and explanations. Provide feedback on their problem-solving strategies and encourage them to continue practicing these skills in future lessons.
