Chess in particular. We played that the new player could swap sides at any time.
The card game 'concentration.' Having a word of the day that everyone tries to work into general conversation flow.
Hangman
Even tic tac toe for young children...anything where you have to keep track of stuff.
Another approach is to work on how to develop systems that decrease the demand for WM. My recent blog post have been all about that. Basically when info gets so well learned that it goes into long term memory as one chunk you can handle lots more without going over thw WM limit. For example a n area code may be 3 digits but it only occupies 1 chunk once it becomes familar.
You can teach kids to develop their own routines and monitor and refine then. What a life lesson!
