Pre-teach some new words your students might come across on the flashcards. Or you may leave them for the students to guess with the help of pictures.

Copy the sheet and cut it into flashcards. Take a card and put it face-up on the table. Each player has his own set of cards or you can shuffle the dominoes between the players (they'll take turns). The first player to start puts the domino  next to the one on the table (either before or after). It must match the word or the picture. If any player cannot put a domino down, it's the next player's turn. 

The first person to play all his dominoes is the winner. The others continue playing. 

Idially all the dominoes form a circuit. If it doesn't the pupils should look for a mistake.

Circulate to monitor and check.

After the game you can enlarge the copies and use them as bigger flashcards to show in class.
