Questions as we get started?
Getting Loopy Unplugged Activity(Course 2, Lesson 5) • I need a volunteer to come up and follow my directions.
• I need a second volunteer to come up and follow my directions.
Getting Loopy Unplugged Activity
• Which of those sets of instructions was easier for me to ask?
• Which of those sets of instructions was easier for the volunteers to follow?
• Would your answers have changed if I had wanted the volunteers to do it 100 times?

Getting Loopy Unplugged Activity
• If I want you to perform the same operation multiple times that’s called “looping” because we “loop” over the same command multiple times.
• When I know in advance how many times that I want you to do something, it is easier for both of us if I just ask you to “repeat it that many times”
Getting Loopy Unplugged Activity
• Can you think of some other things that we could loop?
Let’s have a DANCE PARTY!
Getting Loopy Unplugged Activity
• What would the dance look like if we only repeated the main part 2 times?
• What about 100 times?
• Could we use the same loops with different dance moves?
• Can you think of any dances that are done inside a loop
Where COULD we have used loops?
