I did this last year and did it again this year. I originally started with about 15 balloons counting down school. In each balloon is a slip of paper with an activity that the class gets to do the next day if we have a good day. Today's balloon was to have a "slumber party" in the classroom. I have students bring blankets and pillows and we spend the entire day on the floor for our last day festivities. The students really loved it last year and I'm sure they will again this year! (The last balloon has my age in it because for some reason this class is incredibly interested in how old I am!)
I'd seen the sunglasses with lines on TpT (It does cost money, but this is the link!) so I broke down and spent the $2.50 for the template, bought some big poster paper and let the kids' imaginations run wild!
In the glasses they had to write 2 paragraphs about what they are doing or would like to do this summer. Then they were to draw themselves doing something they mentioned in their paragraphs.
These are only a couple of them, but they are turned out really great and I think the families are going to be excited to see these too!
Many of my students didn't get yearbooks so each year I do keepsake books where they write about their friends and their favorites. I posted the link for it on my post last year if you're interested!
