Attached are the instructions for your garden variety game of ‘memory’ using a standard deck of 52 cards. Start with this, but you can also find similar card games in toy stores. Start with 4 cards if you have to, then work up to grids of 5×5 or larger. Use two decks if need be. This can be played anywhere and for any length of time, and is easy to just throw in as a nice distraction here and there during the day.
