Mime the adverbs

1. Think of a manner adverb (e.g. slowly, secretly).
2. Tell it to the whole class except for one student.
3. This student should give a command to one of the others, for example: "Get up and turn round!" and guess the adverb.
4. If the adverb is 'slowly', the student will do the action slowly.
5. If the guesser cannot identify the adverb, he or she should give another command to someone else - and so on, until the word is guessed.

Alternatively you can tell the adverb to one student, and he should perform the commands of the class in the manner of this adverb, so the class could guess the adverb.
