Engage your students, promote your school and support a worthy cause all with Facebook Check Ins.  There are several ways you can approach this.  Several schools and gyms have offered free water when you check in with Facebook.  We have decided to donate to a local cause when a student checks in.  It is a Win-Win fro everyone.  The student feels good that they supported a cause, the school gets the publicity on Facebook and the local cause gets a charitable donation.
