I recently taught this lesson to a group of 7th and 8th graders in an Advanced Technology course. The students have completed all of the previous lessons in this unit. The warm-up discussion was focused on what we learned in lesson 9 and helping each other understand what “data” is. We then went on to the Activity Guide. I had each student complete a paper copy of the Activity guide. The first and second question on the guide went very smoothly. We had discussions about each chart/graph and the data it was presenting. The final Locker question was a more lively question because of the personal opinion of how important other friends are. An excellent addition too “needed data.” We wrapped up the day taking a class survey about who selected which locker and why.
