frozen juice can lids or circles of cardboard,paper,glue,ribbon,staples,markers,glitterCut a circle of paper a bit smaller than the size of the juice can lid. Glue the paper securely to the center of the lid. Decorate this with markers, crayons and glitter. They can write things like their names, #1, Winner, etc. They can also draw a picture of the Olympic Rings (blue,black,red,yellow,green). Measure a length of ribbon that will fit around the child's neck. Attach the two ends of the ribbon to the back of the medal and secure with glue and/or tape. You can also use a circle of heavy cardboard in place of a juice can lid, but the lid gives it a little more weight.
