Usually, when I work with teachers and mention Power Point, they immediately think of creating a presentation slide show about something. They think final product, instead of thinking tool. So I was really happy to help my second grade teachers use Power Point as a tool to help teach cardinal directions. The students were charged with writing steps to decorate a Christmas tree. The twist was that they had to give directional instructions, such as place the bell southeast of the red ornament. Of course we threw in the fun aspects of Power Point (animations and backgrounds) which is always engaging for students.
I sent them the first two pages, and they duplicated the second slide each time they added a decoration. Another variation on this activity that is not holiday related is to give directions describing where things are on the playground. Both files can be downloaded here.
