A Problem Solved With Math?

Everyday after I pick up the kids the argueing begins. I know it's mostly because everyone is tired, but It drives me crazy! Someone touched someone and it begins. Anyway, I've decided it's going to stop or at least diminish a little. The usual discipline was not having any long term effects. If they got the spoon, it might last a few minutes. If they got grounded from their TV and computer time, they'd just find something else to do. So, needless to say, I needed something different. I prayed for wisdom and came up with this while driving home with my ears ringing from the whining and fighting. They get One warning ( if I feel they deserve one) after that it's math problems. McKinley gets long division. Brandon gets a multiplication sheet. Madelyn gets an Addition and subtraction sheet. It worked like a charm yesterday, and I've got my sheets all printed out and ready for today. I figure it's a win win situation. Either they'll be really good at math or they'll quit fighting. Fingers are crossed, but I hope and pray this works. If not, I'm going to invest in a case of earplugs.
