31 More Days...End Of Year Question

WOW!  This year has flown by.  The students only have 31 more school days.  Our last day for students is May 24.  The last day for teachers is May 25.  How many more days do you have?

Last year I taught kindergarten and we did an ABC countdown.  You can read more about that here.  

My question:

Do you do any type of countdown to summer?  If so, what?  I am looking for ideas for my second graders (soon to be third graders).  Please email me or leave me a comment with your ideas or links to any products or posts that will be helpful.  If there is enough interest I can combine all information into a singular post of maybe a linky party.  Just let me know what works best for you!

Thanks for any help you can give me!
