This is excellent manners training material that the kids will love and respond well to. It is available here on Etsy.
It has 20 different adorable monster cards. Each card teaches a different table manner concept. Included with the cards is additional incentive materials, like Monster Money Bucks and a cut and paste wallet for them to keep it in. Use the Monster Bucks to reward them for good manners and let them spend it on incentives that you want to offer like extra TV time, a trip to the park or anything you can think up.
fIt also included a darling 8.5 x 11 poster that you can frame or make into a plaque that looks vintage and cute for decorating the kitchen while reinforcing the manners.
My kids love it. The adorable monsters really make it lovable and fun. Great for girls or boys.
