What a brilliant use of new technology. If you have access to a mobile phone you now have access to a built in compass. Or if not, you can easily download one. These 4 photographs show what North, South, East and West look like on a mobile phone compass.
Using your mobile phone, you can go on a daily direction walk with your students. Find where due north is in your school playground. Repeat for each of the other main compass points. What about NW and NE? There are 8 compass points waiting for your attention. At the end of the week check your students understanding of the 8 compass points by calling out a direction and asking them to stand exactly where they estimate this to be with their hands pointing to the direction. Check with your iphone. Award a certificate to those students who feel totally comfortable with how to orient themselves around the school.
