This lesson focuses on introducing students (primarily 5th graders, but could be modified for younger or older students). It is helpful to know a bit about topology before teaching this lesson so you can properly explain it to students. There are many different resources for topology at different levels, but I found the topic to be very engaging and hands on, thus the students enjoyed it! (especially the ViHart video about Wind and Mr. Ug for mobius strips) You may separate parts of the lesson and do them rather as short activities if that works better too. They do build off each other, but not so much that they need to be done all at once.
