You will need to put students into groups of three. Two students will play, while the third acts as the referee.
Student A chooses a box from the puzzle grid and makes a sentence using the required form. For example, the verb with its appropriate preposition, or the correct form of an irregular verb. The referee checks the answer sheet and if A’s sentence is correct, marks the box on the puzzle grid with an A, if A’s sentence is incorrect then the box is marked with a B. Student B then plays and the game continues until a student manages to connect four boxes in a straight line, horizontally, vertically or diagonally.
Make sure students play this game at least twice so that student C can also take part.
Try repeating this game a a couple of weeks later to see how much students have retained.
