If I may offer an idea that worked for my husband when he taught middle school (lower SES, only an hour a day with each class)... try lowering your voice, instead of raising it. Then reward the kids who respond, and ignore those who don't. He said he found it made the kids more likely to pay attention across the board, because they never knew when an opportunity for a reward might be coming, so they just had to listen to everything he said.
Of course, he also thought that he had an easier time as a man, compared to his colleagues. Many of the kids lacked a male presence in their lives, and craved his attention more than that of their female teachers.
Yes, great advice here. I used to do the same, although I'd ding a bell or blink the lights to get their attention first. Moving around the room, quick feedback/rewards for appropriate behavior, and a good behavior management system based on earned points, etc. with a chance to regain any points lost will make such a difference. It also helps to only take away portions of recess as a consequence and not the whole time.
