This is an introductory ice-breaking activity for students from grades 6-12.
I have used this as a beginning of the year activity in my High School Physics classes for all grades and achievement levels. It would be fine for Middle School classes as well. It can be given to pairs or small groups of students to get them cooperating on the very first day of class. Since completing all the examples would usually take several tens of minutes, I usually only devote about 5 - 10 minutes to this activity during class, but encourage students to bring it home and complete it with friends and family. We usually have fun the next class day sharing answers that we have come up with. There are often creative or unexpected versions of answers that students suggest for these as well.
