I find this is a good way to revise grammar and get the students to teat each other.
Photocopy a basic snakes and ladders board game (Cutting edge teachers book at starter/elementary and pre-int) has a copy in the back of it, or use a real board if you like.
one of the square should have a question mark on them (or all of them if you like!). When a person lands on a question mark, they must take a card which has a question on it.
It’s a good idea to get the students to make the question cards which revise all of that week’s/month’s/course’s vocabulary and grammar. Jumbled sentences, gap fills, collocation and conjugations also make good questions. The students grade the questions as they are focusing on the topics covered in their class and it also provide a fun way to revise on a Friday rather than a normal gap-fill exercise!
I’ve done this with a variety of levels and ages and it has always worked well – the students feel challenged as they spend the first part of the lesson writing questions but spend the second half in a more fun frame of mind “playing a game” and learning.
Let me know how it goes!
