When I taught first grade, I had a very chatty bunch of students. I used this in conjunction with the warm fuzzy classroom management system. Just type your students' names in the chart, print (on tabloid size paper) and laminate. When students get too chatty, they get an X in their box. Dry erase marker works great if it's laminated. Since I used the warm fuzzy system, they treasured their fuzzies... if they had zero checks they got 3 fuzzies at the end of the day, one check they got 2 fuzzies, two checks 1 fuzzy, and three checks got 0 fuzzies. It worked quite well for that groups of kids!
