One of my favorite teaching tools is this cupcake holder. I found silicone baking cups as a reusable snack container and purchased one for each student. I load the cups with snacks and fasten the lid onto the container. The lid seals so the snack won't get stale, and keep out any undesirables. Before snack time I bring this container out and each student picks up his/her snack. It has shaved at least 10 minutes off snack preparation time.
