I write U.S. Mail on the bags and the children enjoy putting mail in their bags and delivering to others. I like to make a post office box for the children to sort the mail into. I take half gallon milk cartons and staple 5 together side by side. I then add another row of 5 stapled milk cartons on top of the first row and again staple them all together. The slit on the top of the box makes a great mail slot for the children to drop their mail into.
Children also enjoy doing plunger painting with small plungers bought from the dollar store.
Most students who are studying to be dentists, dental hygienists, or dental assistants or required to do so many community training sessions. They will come to your school to teach your students in a fun way about proper dental care and they will probably get a bag with a new toothbrush and other dental goodies to take home. They also make great visitors for community helper month. During Community Helper Week we discussed several helpers. Two of which were the grocer and a chef.
