All About Me Bags - use the first week of school, grades Send kids home with bags, have them return with the bags. Place in basket and have each child introduce themselves, a fee at a time throughout the day, when there is time.
All about me bag - Each child fills the bag with 4 things about them and brings it into school. They can decorate the bag too. I did this with my own items as a first day of school ice breaker. Maybe get large paper sacks from the grocery
