For my after school class I made a deck of cards with vocab from the last couple months and then taught them to play the card game Spoons. These kids are 3rd and 4th grade but pretty bright and they caught on really quickly and enjoyed it a lot. However, I think any grade would enjoy a game of Spoons.
You can change how the scoring works...some people prefer to spell a word if you don't grab a spoon, or are out automatically.
I had 108 total cards with 6 of each vocab word. Some rounds went longer than others.
Hope this explanation PPT is helpful!
