Are you looking for productive tasks your fast finisher pupils can carry out by themselves in between two classwork activities?
Here is one of them.
A British idioms memory or guessing game cards set listing 20 popular idioms used in the English language.
You just have to print, laminate , cut the cards and leave them at pupils' disposal.
How to use the set of cards:
1) Use this set of cards as a memory game. Pupils shuffle the idioms cards and definition cards, and place them in front of them face down. Each player reveals a pair in turn. The player with the most cards wins the game.
2) Use this set of cards as a guessing game. Pupils split the set in two different piles: idioms in one, definitions in the other.
Players share the idioms pile. In turn, each picks a definition and reads it aloud: the player in possession of the corresponding idiom who recognizes it fast enough wins the pair.
3) Plenty of other games can be thought of !
