Now, don't we all struggle with the blurting out in class?! Two summers ago I went to a training at ACU, and one of the teachers there showed us how to make these wonderful little behavior modification tools to help with blurts, and it has sure helped me out!
I hate to embarrass the kids, so I keep this pretty light. Every time a student blurts out, they have to put a "blurt" on this chart. They have three chances. I usually go by a three-strikes-you're-out policy before I sign their folder and take away some recess time.
All it takes is poster board, velcro dots and whatever image you want to use for the "blurt" that they put on the chart. (I used an image from Boardmaker.)
Make a spot for each child's blurts and attach three of the velcro dots...
Each little blurt needs its own velcro dot, so that they can grab one out of the bag and attach.
At the end of the day, I make note of who had no blurts that day. I usually do an extra prize for any student who goes the entire week with no blurting out! I've also found that if I am really consistent with this during the first 6-8 weeks of school, then I hardly use it after that. This tool has really helped my students manage their own behavior when it comes to blurts!
