I saw people using "Brag Tags" and loved the underlying idea of rewarding students for all types of reasons, but wanted to make my classroom tags really goal, state standards, and attendance centered. In this packet of read to print tags you will find 9 categories including: Arizona Science Standards, Monthly Attendance, 1st day of school (which is a huge accomplishment for the younger grades), Exceptional Sportsmanship, School Pride, Memorization of Military Child's Creed (this could be edited for something your students need to memorize), Benchmark Testing, Multiplication and Division Masters, and Running Achievements.
I made these relatively simple and printed them out on colorful cardstock so they would hold up on the students S.W.A.G. chains (dog tag chains). Just print, cut, punch a hole, and hang!
