Students are doing a crocheting service project by crocheting scarves for people, who might not be able to afford winter wear. This will make a difference to them because it will protect them from hypothermia and frostbite. It will keep them warm and comfortable. The students have learned two types of stitches, the chain stitch and the single row stitch. The class is connecting this to math by measuring the area and perimeter of the scarves.
