Another activity which can serve as a warm-up or the whole revision lesson. It’s all up to you. You can revise both vocabulary and grammar with your students at the same time.
First, show your students some examples (easier and more difficult ones are included in the presentation below) of definitions of words or phrases you want to revise – let the students guess them.
Secondly, ask your students to make definitions themselves and let their peers guess. You may ask them to make just one or two definitions if you want it to be just a warm-up; or more if it is to be a longer revision.
Then show the students these words in context and ask them to paraphrase the sentences, translate, fill in the gaps, whatever you want.
Finally, students are supposed to prepare their own paraphrases, translations, gap-filling tasks, etc with the words and phrases they prepared in stage one. Quite a challenge even for advanced learners.
