Objectives: 1.Solve a problem by applying the problem-solving process. 2.Express a solution using standard design tools. 3.Determine if a given solution successfully solves a stated problem.

Work in groups again and solve this problem: Assume there are 10 people in a room, including you. Each person in the room must shake hands one time, and only time, with all the other people in the room. How many handshakes will occur? If there are 20 people in the room, how many handshakes will occur? If there are N (where N > 0) people in the room, how many handshakes will occur?

Understanding the problem: – What data of information is known? – What is unknown? – What are the conditions? Plan the solution: Show your plan for solving this problem. Carry out the plan: Using your plan, show your work and your solution. Review and discuss your solution: Reflect on your solution.

Review your grade – I will fix any errors but am not accepting new work.
