Members who actively participate in the construction of the paraphrase will get +5 points. Each correct paraphrase will be +1 point. The members of the team that compose what I judge as the "ultimate" paraphrase for that sentence will get +5 points.
You may want to have a thesaurus open for this activity.
Each paraphrase must be accurate i.e. same tenses and meaning.
Original: This shirt is too big for her. -> She was too big for the shirt. Not a good paraphrase, as both the meaning and verb tense have changed in the example.
Each paraphrase has to have more than one change.
Original: This shirt is too big for her. -> This shirt is too large for her -> This blouse is too big for her. -> This shirt is excessively big for her. None of these are good paraphrases as they only make one change.
