Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Create a number of instruction cards along the following lines: the word must be a past tense form, the word mustn't have more than one syllable, it must be something you can find in a supermarket, the word must be an adjective etc. One student takes a card and reads the instructions. He / She then starts off by saying a word beginning with 'a', the next student thinks of one beginning with 'b', the next with 'c' and so on. Give all students at least one 'life' or a word pass to use if they get stuck. After they've used up their 'lives', start eliminating and stepping up the time allowed to think of a word. A fun and snappy way to end a lesson.
