We're currently planning our "end of the year celebration" as a grade-level. Each teacher will set up an activity in their classroom, and classes will rotate every 20 minutes. For example, one teacher will have a bunch of puzzles set up in her classroom, and another teacher will have a dance party with "Just Dance Kids" videos playing through the projector. There are 7 classes of 3rd graders who will rotate through my room. I've thought about doing some kind of craft (maybe a short read aloud that ties into it) but with 135 students, the cost of supplies could get expensive. I've also thought about doing a Reader's Theater station. Students could break off into groups of 4 and work on different scripts (I have a lot of fun fractured fairy tale plays). I'd love to hear some of your ideas! Something fun that can be accomplished in 20 minutes without breaking the bank.
