Instructions:

Divide the deck equally among the players. Players place their deck face down in front of themselves. Players take turns turning over their top card and putting it, face-up, in the middle of the table. When the card played can be added to any other card, which has already been turned over, to make 10, a player yells, “snap 10” and takes the two cards. The first player to do so keeps the cards. The element of speed that results from any player being able to be the first to yell “snap” helps to dissuade students from counting. At first, you can play without this speed factor. In this version, instead of having any player shout “snap 10” only the player who places a card should look for a match and can “snap” the match. The player who takes the cards says the number sentence such as “2 and 8 make 10.”

Whoever has the most cards at the end, wins.
