You can also use bang bang clap with vocab words for each student --- break them down into smaller groups of ten each or so
You could try adapting a form of tag into an English activity
If you break them down (again) into groups of about 10-14 you could play a fly swatter game that lets them race to the board/wall/path of pictures/etc to slap the right vocab word with a fly swatter.
Another good game that one of the other ALTs in my area came up with is a water race game.... you have two teams, each team has a full bucket and an empty bucket of water that are a good 10 m apart (less or more is ok too). They also each have a cup with a small hole in the bottom and a racket (tennis, badminton, racquetball, etc). They have to run, fill up the cup, balance it on the racket, then come back to dump the water in the empty bucket. At the full bucket you have them say the word of a flashcard image/say the target sentence/ask the target question/etc. It is a game that needs to be played outside though....
hope that helps.
My first recommendation was going to be the Hokey Pokey as well though.
