Hi sherr.
We used to play a game called Newmarket (There's probably a proper name for it). You put the four Kings in the middle of the table, shuffle and then deal the rest out.
The person to the left of the dealer plays the lowest card in their hand and then you try to be the person to play the Queen (We used to use 1p and 2p coins - one in the kitty and one on a card). If you can't make a run to the Queen, the last person to play a card then alternates between the lowest Red and Black. The first person to play all their cards takes the pot. If no-one takes the pot then you all put in the kitty again and bet on a card.
Being younger kids you might want to swap out the cash for something else.
