Graduation from a private elementary school is normally accompanied by a well designed ceremony which highlights the achievements of students. While this ceremony is exciting it has some group feeling which lacks the personal sentiment you will want to convey to the graduate. To this end a graduation gift for elementary school aged children that really drives home the importance of this moment is a special dinner with family, maybe even extended family, at a nice restaurant. If the young boy or girl is mature it may even be the restaurant of their choosing.
Have fun thinking about the graduation presents you will gift to your elementary school grads, they will only pass this landmark once in their lives.
