Another idea is if its older kids – like fifth, sixth and seventh graders – you can teach them the “Cup dance” (check Maccabeats Dror Yikra). It’s really fun. I once taught it to a group of fifth graders and they were obsessed – we spent an hour on it and they were doing it the whole week! Sounds weird but if you know it, it really is hard to stop once you start:)
A Talent Show is also a fun idea
