Graduation is something truly significant for those completely the 12th grade, and unnecessary for pre-k, 5th, and 8th grades. I am having the children each carry in a yellow carnation singing You Are My Sunshine, they will give this to their mom. I have them recite things we learned this year. Pledge, Days of the week, months of the year, a few songs, and then I give a brief description of what we did each month. The kids love this reminds them of all we did that year.
Kids love to act like they are older.
You can have a small ceremony and give out interesting awards. Each child should take home an award relevant to their own personality and a diploma. This year, the children are singing and 'dancing' to three songs. I also found a cute song that the parents will sing with them. We will end on that since it is too distracting.
