Matching pairs

From Teflpedia

Matching pairs or concentration is a memory game that is played by having two identical sets of cards that are placed face-down. Players take turn to turn over 2 cards, keeping the cards if they are identical, but turning the cards back over if they are different.[1]

If the face of the card has a picture that elicits target language on it, this can be a good way of practising TL while students mistakenly think the point of the game is to win.
