Each year, my school has a transition afternoon where all the kids go and spend the afternoon in the class of next their next year teacher.
Last year, my kids came up and I had balloons hanging from the ceiling. They asked me what they were for. I explained my class was counting down the 12 days to the Summer holidays by popping a balloon each day. Inside each balloon was a slip of paper that told the kids a special treat they were having the next day (boy, were those kids excited to come to school those last 2 weeks!). Anyway, those balloons have been mentioned a number of times this year, most recently today! I had totally forgotten that I was going to do it again! Just in a nick of time too, because tomorrow is the 12th day to our holidays!
Here's the freebie I posted last year in case you are wanting to use it. Just click on the pic.
