You have green shamrock biscuits. Have ready several small containers of milk to which you have added food coloring. We usually use margarine tubs, and offer the children blue, red, green, yellow and purple. Each child can brush colored mile on the slice of bread, in stripes or a rainbow arc, using a pastry brush or new watercolor brush. Then place in toaster.
Bread comes out colored and can be eaten with butter and jam.
Add food coloring to peanut butter and spread onto two slices of bread. You can either make shamrocks with a cookie cutter or cut the sandwiches into squares. I like to bring in Lucky Charm cereal. I encourage my students to count and sort the marshmallow shapes. They also serve as a tasty snack.
