Don't throw out those handy Altoid tins. When empty, they can be used in many ways. Fill with beans and glue shut for a flat toss piece for games like hopscotch; fill with various objects for discovery boxes; punch or drill holes in ends to hang for wind chimes; thread ribbon through the holes to make a pull toy; glue onto a hard surface to make a permanent concentration game, fill with various small items, close lids and search for matching tins; use for measurement of length, width, perimeter, area; paint and decorate them to make gift boxes; store small magnets inside; glue onto cardboard in the shape of a robot; fill one tin with a prize and distribute to students, play game like pass the potato, winner is the one who has the filled tin when music stops. I'm sure you can think of many, many more uses!
