For this game you will need a deck of cards and the Suma Diez flashcard.
The kid takes 1 card from the deck and places it on number 1 and then take another card and sees if it adds up to 10, if not the card should be placed in number 2. Then, take the next card from the deck. If it adds up 10 that pair goes to the side. If it does not make 10 it goes to the number 3 and so on. If all 4 spaces are filled the next card taken from the deck should be placed on the bottom of the deck.
