1. Watch the following YouTube Video and answer the following questions:
i) What is Problem Solving?
ii) List the steps of Problem Solving.
iii) List at least three benefits mentioned in the video.
2. Using the following scenarios, complete the IPO chart below. Visit this website to understand the use of IPO charts in Problem solving.
Note: You are not being asked to do any mathematical calculations. Determine which parts of each scenario belong under each heading of the table.
i) Kaila is hungry and want to fry an egg. Give her the directions to make herself a delicious fried egg.
ii) Derek's teacher asked him to calculate the average and sum of his last three grades. Help Derek with his calculations.
iii) Leilani wants to find out how much her pay is for the week. She worked 45 hours this week. For the normal 40 hour work week each worker is paid $20 an hour.
