With the final exams approaching students in my high school students are increasingly less focused on conversation based lessons and more on their own revision. I have used the ppt by powelldr to create a grammar game which may help with their studies.
The questions don't necessarily increase in difficulty according to the value of the question. However I did make some attempt for them to do so despite limited time.
For my first class it went down pretty well.
Feedback is appreciated :)
