I've noticed the last 3 days of school my kids don't learn much, if any. I was there volunteering for 1/2 day two of those days this year. They had 1/2 day field day and then a school assembly on Monday, cleaned the classroom for part of the day on Tuesday, and an end-of-school party on Wed (last day of school) which is only a half-day. There was also time for year book signing. My kids had fun, and I want them to help clean-up. However, I would consider taking them out of school for a vacation if they didn't want to go to school those 3 days. Can't imagine them wanting to miss the last 3 days, but it wouldn't have hindered their acedmic learning.
