B.H.
Why not mix up some Cheerios, mini marshmellows, pretzel sticks and goldfish crackers in a bowl. You could put them into individual snack bags or take the bowl to school and let the kids scoop it out with a big spoon.
Other ideas:
Graham crackers and Applesauce or Apple Slices
Animal Cookies and a fruit cup
Tortilla Chips and melted chesse
A fruit and Veggie tray..be sure to bring the ranch
Finger sandwiches cut with cookie cutters.. The teacher could use this as a learning process too.
