This is a great addition to a Parent Back to School Night or Open House. It's a cute way to share with parents a few of the items you have on your classroom wish list.
Parents are always asking how they can help. At Back to School Night I print and laminate all of the mason jars. Then, I display the jars on the table or counter with a chalkboard. While parents are checking out the classroom they typically pick up one or two items.
