Integer Slam

Walt: add and subtract integers up to positive 12 or negative 12.

A pack of cards.
1-3 players.

The aim of the game is to use your three cards to get 12 or minus 12.

Each player gets three cards. The red is negative and the black is positive. Using those three cards they all have to add up to either 12 or negative 12. The top deck of cards goes on top. If you can’t use the three cards to make either 12, there is a discard pile. The next player can take a card from the deck of cards or the discard pile. First one to get minus 12 or positive 12 is the winner.

I need to get a better understanding of how to change a decimal into a fraction.
