Cardo,
As an activity that supplies are very cheap.....I buy a deck of the large cards at the dollar store...And a regular size card deck for the caller... You shuffle out the whole deck of cards between your residents...( So each resident has an equal amount of cards) Then you use the other deck to call out the cards,,,When your resident card is called out they turn the card over ....When one resident has all their cards turned over they have Cardo....I give money out as a prize....50 Cents.... And then you reshuffle your deck and tell the residents to turn their cards over and we will play again.....Cardo is like bingo but with cards I hope this helps..
